CAUTION
GC-2010 may get wet from humidity in some transport conditions. In
such case “drying-out” is necessary to avoid a short circuit at the
heater in the injection port or the detector.
Under some transport conditions, condensation may form inside the GC components. To
avoid injection port or detector heater unit short-circuits, allow the unit sufficient time to dry
after transport, and follow the procedure below after installation.
(1) Seal the injection port and detector without attaching a column. (Refer to the figure
below.)
(2) Remove the injection ports (INJ) and detectors (DET) from all configured analytical flow
lines to prevent the heater from turning ON.
(3) Set the column oven temperature to 300 °C and start the GC.
(4) Keep the column temperature at 300 °C for 2 hours or more.

Q Supply gases
CAUTION
1.Gas supply pressure should not exceed the maximum pressure
listed below.
Excessive pressure may break pressure control valve or other parts.
2.When sharing a gas source with other instruments, check
specifications of all instruments to be used including this unit and
supply gas so that requirements of all the instruments can be
satisfied at the same time.
The following gases and associated purity values are required to maintain the optimum
performance of the unit.
For detectors other than FID and TCD, refer to the instruction manual corresponding to each detector.
1. Gas types
•Carrier gas types
(Packed FID analysis)
Both helium and nitrogen can be used. Nitrogen is more reasonable in terms of price.
(Packed TCD analysis)
Using helium or hydrogen as carrier gas helps analyzing other materials at high
sensitivity. Because hydrogen is flammable, helium is generally used for safety.
However, to analyze helium or hydrogen, use nitrogen or argon as carrier gas. Nitrogen
is convenient to analyze minor components in the air because the nitrogen peak is not
detected when it is used as carrier gas.
(Capillary analysis)
Helium is the most suitable for separation.
Although nitrogen, which is more reasonable than helium, can also be used, the optimum
separation conditions may not be reached.
2. Gas purity
Helium (carrier gas, makeup gas) : 99.995 % or higher
Nitrogen (carrier gas, makeup gas) : 99.995 % or higher
Argon (carrier gas, makeup gas) : 99.995 % or higher
Hydrogen (FID detector gas) : 99.995 % or higher
Air (FID detector gas) : Dry air (oil and other organic components eliminated)
Compressed air(must be suppressed by an oil-free
compressor and dehumidified)

WARNING
HYDROGEN GAS PRECAUTIONS
Hydrogen can explode if it is allowed to accumulate in a poorly venti-
lated area.
1.Connect gas lines correctly. Hydrogen is released into the room if
the tubing is accidentally connected to the air inlet.
2.When the unit is not in use, close the main valve of the hydrogen
gas cylinder. Check for leaks at the main valve.
3.Every time the unit is used, check for leaks along the flow line from
gas cylinder to the unit interior.
4.To prevent an explosion due to a hydrogen gas leak, the room in
which the unit is used should be well ventilated. Prohibit the use of
open flame in this room.
5.Close the main valve of the hydrogen cylinder immediately after
completing the analyses. Then, turn OFF the unit and perform
normal shut-down procedures.
WARNING
HYDROGEN GAS HANDLING PRECAUTIONS
The accumulation of hydrogen gas inside the column oven can cause
an explosion.
Close all hydrogen regulator valves not in use and stop gas supply.
(When a manual regulator valve is used, turn its control to make the
pressure zero. For APC, turn off the APC for hydrogen gas.) Seal the
column connection.

CAUTION
Hydrogen gas supply precautions
Make sure that the supply pressure to the flow controller does not
exceed 500 kPa.
If the flow controller fails with a hydrogen gas supply pressure over
500 kPa, a dangerous situation exists. Lange amounts of leaking
hydrogen could cause the FID flame to expand out of the detector.
Hydrogen gas is lighter than air. If it leaks, it can accumulate near the
ceiling. Pay strict attention to ventilation so that leaking hydrogen is
vented out of the room and cannot accumulate.
WARNING
Hydrogen carrier gas precautions
If much hydrogen gas is released into the poorly ventilated room, it
may cause the explosion.
1.In order to prevent hydrogen gas accumulate in the room, attach
tubes to split vent, purge vent, TCD vent and ECD vent. Discharge
the gas to open air or a ventilation equipment (such as the draft
chamber).
2.Install the GC in the well ventilated area. (Ex. in the draft chamber)
3.In order to measure hydrogen gas concentration, equip a hydrogen
gas sensor in the room. Keep the hydrogen concentration low.

NOTE TCD signals do not necessarily have a plus peak because they are determined by relationship of heat
conduction between a substance to be analyzed and carrier gas. However, the data processing unit
normally calculates the area of a plus peak. When a minus peak is detected, “signal polarity” needs to
be inverted into a plus peak. In this case, inject a sample into the opposite inlet of the one instructed on
the popup screen shown below.
“Signal polarity” can be changed using the time program during analysis. (For detailed descriptions

. 4.4 Capillary TCD Analysis
To perform capillary analysis using a unit with the TCD, makeup gas needs to be supplied to
the TCD joint that a column is connected to and carrier gas (called reference gas) also
needs to be supplied to the TCD joint that a column is not connected.
In order to supply makeup gas, install the detector adapter with purge (P/N 221-34012-91) to
the TCD joint. Connect the purge piping of the adapter to the dual INJ so that makeup gas is
supplied from the dual AFC through the dual INJ.
(The dual AFC is off the line and operates as an independent mass flow controller.)
Reference gas is supplied from the dual AFC when the dual INJ and TCD are connected
with a MF-MF joint.

Confirm that the septum and insert are properly attached.
Check dirt on the septum and the number of injections and replace it
when necessary (after approximately 100 injections).
Column preparation Attach the column to the injection port and detector correctly.
When the above preparations are complete, turn ON the GC (power switch on the lower
right side of the GC).
Set the column information Set parameters on the [FLOW] key screen. Set the column inner diameter,
and the flow rates column length, and the film thickness on [Column] (PF menu). For
the SPL and WBL, set the purge flow rate on [Purge] as well.
(When the column flow rate is set by the AFC, changing the column
temperature changes the column flow rate.)
Set the temperature of the Set the temperatures on the [INJ] and [DET] key screens. (If the detector

the allowable column and detector ranges.
Start GC control Press the [SYSTEM] key to display the main screen.
Press [Start GC] (PF menu) to start GC control.
Press the [MONIT] key, and ensure that the temperature of each
zone, the gas flow rate, the gas pressure, etc. are correct.

. 5.2 Notes for Analysis
Q Analytical column
・ Make sure that carrier gas is flowing through the column before increasing the column
oven temperature because the column cannot separate compounds properly when its
liquid phase is oxidized. This is especially important for polar columns. Press the
[SYSTEM] key and set a start time so that carrier gas flows for the set time prior to
temperature control of the heated zones.
・ Selection of the analysis column is very important in GC analysis. In general, select a
liquid phase whose polarity and chemical characteristics are similar to those of the
analysis target compound to obtain good peak shape. However, highly polar columns
require low temperatures and do not last long.
Therefore, when analyzing an unknown sample, begin by analyzing it on a neutral column
with a higher allowable temperature limit. Switch to a more polar column if necessary.
GC-2014 63

5.2 Notes for Analysis
Q Injection counter
The injection port septum and the glass insert are required to be inspected and replaced
periodically. The GC-2014 probides a function which counts the number of injections. When
the number of injections exceeds the limit, you are prompted to perform maintenance. (What
is actually counted is the number of START times.)
Select the analysis counter on the [DIAG] key screen to set and reset the counter limit. Set
the limit to perform maintenance on a regular basis.
The septum/glass insert replacement cycle varies, depending on the analytical conditions
and samples. If the glass insert is easily contaminated (when analyzing non-volatile com-
punds for example), set a low counter limit. On the other hand, when analyzing cleaner sam-
ples, the limit can be increased.
Q Starting up the GC
Turn on the power and/or press the [SYSTEM] key to display the GC starup screen. On this
screen, specify the files used for instrument startup and instrument cleaning (column bake -
out).
Press [Start GC] (PF menu) to start temperature control of each heated zone accoding to the
parameters set in the file.
A start up method should be used to initialize the system once it has been turned on. Set the
start up method to “auto” to start the file as soon as the power is on; this helps with instru-
ment recovery after a power failure.
The initial step in the startup method should be turning on the carrier gas flow. After a set
time, increase the injection port and detector temperatures. The column oven temperature
can then be set to increase. The oven temperature increases last to protect the column from
damate and the detctor from contamination. The GC-2014 is designed to control the temper-
atures so that the column temperature never exceeds the detector temperature, even if all
temperatures are set to increase at the same time.
A clean up method uses higher oven temperatures than those used for the analysis. After
set bake-out time, return the temperatures to their normal analytical parameter.

The following examples show various situations where STOP TIME and FLOW OFF TIME
can be used effectively.
• After the end of an analysis, each heated zone is cooled. Once the column over is
cool, carrier gas flow is shut off.
STOP TIME = 0 minutes
FLOW CONTROL = End
FLOW OFF TIME = Approx. 20 minutes
• A column is conditioned, then the column over is cooled. Carrier gas flow is then
shut down.
STOP TIME = Column conditioning time
FLOW CONTROL = End
FLOW OFF TIME = Approx. 20 minutes
• At the end of an analysis, each heated zone is cooled, but carrier gas is kept flowing
for rapid equilibration for the next day’s analysis. The next day, the system is automati-
cally restarted (15 hours = 900 minutes later), and temperature control resumes.
START TIME = 0 minutes (because the carrier gas continued to flow)
STOP TIME = 0 minutes
FLOW CONTROL = Cont (to keep carrier gas flow on)
RESTART GC = On
SLEEP TIME = 900 minutes (at the end of the SLEEP TIME, the GC
restarts)
• At the end of an analysis, each heated zone is cooled, and the carrier gas flow is
stopped once the column oven is cool. The following day (15 hours = 900 minutes
later), carrierr gas flow is turned back on and temperature control begins.
START TIME = 10 minutes (because carrier gas flow was off)
STOP TIME = 0 minute

Press the [SET] key to display the main screen shown in Fig. 8.1.1 and to make frequently
used parameter settings.
To make changes to the [COL], [FLOW], [INJ], and [DET] parameters, the [customiz] (PF
menu) key is pressed. Changes to these parameters are reflected in the [SET] key main
screen.
The screen shows parameters of a line that consists of an injection port, detectors, and
options connected to a column (two columns for the dual packed column INJ). The combina-
tion can be changed on the [Line Config] (PF menu) sub screen.
When the system is turned on, the temperatures are controlled for the components in the
flow line. If the AFC is present, carrier gas is supplied to the injection port specified. If APC is
present, detector gases are supplied to the detector specified.Temperatures are not con-
trolled, and gases are not supplied, to components which are not part of the analytical flow
line. Although two or more detectors can be set for a line, only one injection port can be set.

When the SPL, etc. (AFC) is used
INLET PRESS
Range: 0.0−970.0 kPa (Refer to Fig. 12.2.5.), Default: 100.0 kPa
Sets the column inlet pressure.
The initial pressure must be set in order to create a pressure program.
When the control mode is set to “pressure”, the system keeps the column inlet pressure at a
constant value while the oven temperature program is running.
COLUMN FLOW RATE
Default:1 1.00 ml/min
Sets the carrier gas flow rate at the capillary column exit (atmospheric pressure at 25 °C).
When you set the carrier gas flow rate, the system calculates the column inlet pressure
based on the inner diameter and the length of the column. The column flow rate is set
separately so that the carrier gas flow rate desired occures at the initial temperature in the
oven temperature program.
LINEAR VELOCITY
Default:2 30.0 cm/s
Sets the average linear velocity of the carrier gas flowing in the capillary column.
When you set the linear velocity, the system calculates the column inlet pressure based on
the inner diameter and the length of the column. The linear velocity is set separately so that
the linear velocity desired occures at the initial temperature in the oven temperature
program.
When the control mode is set to “linear velocity”, the column inlet pressure automatically
changes so that the linear velocity remains constant even while the oven temperature
program is running.
TOTAL FLOW RATE
Range: 0.0−1200.0 ml/min (Refer to Fig. 12.2.5.), Default: 500.0 ml/min
The total flow rate varies depending on the injection mode as follows:
In split or splitless mode, the total flow rate is equivalent to “column flow rate + split flow rate
+ septum purge flow rate”.
In direct mode, the total flow rate is equivalent to “column flow rate + septum purge flow rate”.
SPLIT RATIO
Range: -1.0/0.0−9999.9, Default: -1.0
The split ratio is “split flow rate / column flow rate.”
When you set a split ratio, the system sets the total flow rate based on the calculated carrier
gas flow rate and split flow rate, so that the desired split ratio occurs at the oven
temperature.
Set the split ratio to “-1.0” to fix the total flow rate regardless of the oven temperature.

. Packed Column Injection Port (Dual INJ)
12.1
During analysis using packed columns, a sample is injected into an injection port and the entire
evaporated sample is injected to the columns. A mass flow controller is used to control the
column flow rate so gas is supplied at a specified flow rate even when the column flow path
resistance and temperature change.
The GC-2014 packed model has an injection port that two packed columns can be attached to
(dual INJ) as standard. An injection port that only one column is attached to (single INJ) is
available as an option. For the single INJ, refer to its instruction manual.

The linear velocity is set separately so that the linear velocity desired occures at the ini-
tial temperature in the oven temperature program.
When the control mode is set to “VELOCITY”, the column inlet pressure automatically
changes so that the linear velocity remains constant even while the oven temperature
program is running.
SPLIT RATIO
Range: -1.0/0.0−9999.9, Default: -1.0
The split ratio is “split flow rate / column flow rate.”
When you set a split ratio, the system sets the total flow rate based on the calculated
carrier gas flow rate and split flow rate, so that the desired split ratio occurs at the oven
temperature.
Set the split ratio to “-1.0” to fix the total flow rate regardless of the oven temperature.
TOTAL FLOW RATE
Range: 0.0−1200.0 ml/min (Refer to NOTE 1), Default: 500.0 ml/min
In split or splitless mode, the total flow rate is equivalent to “column flow rate + split flow
rate + septum purge flow rate”.
SPLIT MODE
Selection: SPLIT/SPLITLESS/DIRECT, Default: SPLIT
SPLIT: Controls the column inlet pressure and the total flow rate so that the
column inlet pressure and split ratio occur as specified.
SPLITLESS: Closes the split flow line during the sampling time so that the set column
inlet pressure is controlled by the Total Flow Controller.
Opens the split flow line and controls the Electronid Split Controller so that
the preset column inlet pressure occurs (Refer to Fig. 12.2.2.) after the
sampling time elapses.
DIRECT: Closes the split flow line and the set column inlet pressure (in pressure
mode) or the set total flow rate (in flow rate mode) occurs. When making
direct injection analyses, select WBI in the setup screen so that SPLIT
mode is not available.
SAMPLING TIME

If the injected sample consists of a solvent with a high vaporization expansion coefficient,
the pressure inside the injection port drastically increases when the solvent vaporizes. This
can result in too much solvent being diverted from the column, reducing sensitivity.
Sending power to the split flow valve at sample injection can keep the split ratio at its desig-
nated valve.

. Setting the Flow Rate Parameters
12.5
Fig. 12.5.1 Effect on linear velocity and HETP for various carrier gases (H-V curve)
The graph above shows that the lowest HETP values are obtained when nitrogen is used as
the carrier gas and the linear velocity is set to a value a little less than 10 cm/s. However,
nitrogen is not a good carrier gas for capillary analysis for the following reasons.
(1) If the linear velocity deviates only slighty from the optimum value, the HETP increases
dramatically.
(2) To obtain the optional linear velocity, the flow rate must be low, resulting in long analysis
times.
Helium is frequently used as the carrier gas because the HETP is low over a considerably
wider linear velocity range starting at 20 cm/s.
The column efficiency of hydrogen is good at higher linear velocities than for helium. For this
reason, hydrogen can be used for rapid analyses. However, hydrogen is seldom used in
reality because it is extremely flammable, and therfore too dangerous.
Q Efficiency of an analysis
Usually, analyses are performed with a flow rate that is higher than the optimal flow rate, as
long as separation of conpounds is sufficient. This reduces the analysis time. For general
analyses on this system, setting the linear velocity to 30 cm/s is recommended.
The tables below show the column inlet pressure at which the linear velocity becomes
approximately 30 cm/s. Use the tables as the guideline for setting the column inlet pressure.
However, the inlet pressure also depends on the column type.

Fig. 13.2.1
The TCD sensitivity is proportional to the difference in thermal conductivity between the
sample and the carrier gas. Because the thermal conductivity of the sample is lower than
that of the carrier gas, the TCD sensitivity increases as the thermal conductivity of the carrier
gas increases.
For high sensitivity analysis, use helium with a purity of 99.9995 % or more.

SIGNAL POLARITY
Selection: +/-, Default: +
When analyzing compounds with a thermal conductivity higher than the carrier gas,
baseline peaks are inverted (negative). When this occurs, switch to a polarity of “-” to
produce positeve peaks.
CURRENT
Range: 0−200 mA, Default: 0 mA
The TCD sensitivity is approximately proportional to the cube of the current.
If the sensitivity is insufficient, increase the current within the range shown in
Fig. 13.2.3. The maximum operating current is determined by the detector temperature
and the carrier gas type. Keeping the current highre than necessary shortens the fila-
ments life and can cause baseline drift.
CAUTION
If the current is turned on before the carriergas + make up gas has
completely replaced the air, the filament can be blown.
Ensure that the current is set to “0” at first. Press the [SYSTEM] key
main screen, allow carrier gas to flow for approximately 10 minutes,
then set the current.
CAUTION
To avoid broken filaments and poor performance, set the current
below the valves indicated by the curves below.

This assosiates the flow controller to an injection port.
Q Detector gas flow controller settings
When installing detector flow control units, the names DET#1 to DET#4 are
automatically assigned starting with the one nearest to the GC.
Specify the to flow controller detector gas settings for each detector No. (DET#1 to
DET#4).
CONT. TYPE
For display only.
The type of each installed detector control unit is automatically recognized and displayed.
DET APC No.
For display only.
When the slot No. is selected for each installed detector gas flow controller, the name
DET APC 1 to DET APC 4 is automatically assigned to each flow controller.
UNIT TYPE
For display only.
When an APC is installed, the APC type is displayed for the Slot No. selected.
“APC (1ch)” indicates an APC for ECD/TCD. “APC (2ch)” indicates an APC for FPD.
“APC (3ch)” indicates an APC for FID/FTD.
When manual flow controllers are selected, “DET GAS” is automatically displayed.
SLOT NO.
Selection: NON/SLOT2−6/MSLOT1−7, Default: NON
When a manual flow controller is installed, specify the installation location slot no. from
among MSLOT1−7.
When a APC is installed, select an available Slot No..
Slot No. which have already been set cannot be selected.
When CONT. TYPE is WDFID (for dual FID) or TCD-L (for packed TCD), two DET APC
numbers and slots are displayed. Only the upper lines can be set. When a manual flow
controller is used, enter the smaller slot no. among the pair (2 slots). (Example: If
MSLOT4 and MSLOT 5 are available, specify MSLOT4.)
Two units of the same type of APCs need to be installed on slots next to each other
because piping for two units is set. An APC for the L side is installed on the slot with the
smaller number so set the slot no. on the L side to the upper line. An APC installed on
the next slot is automatically set on the R side. For example, when the L side is set on
SLOT4, the R side is set on SLOT5.
Setting slots for TCD-L detector gas is unnecessary because makeup gas is usually not
used for packed TCD.
HEATER PORT
Selection: NON/INJ1/INJ2/DET1/DET2/AUX3/AUX4/AUX5, Default: NON
Specify the detector heated zone where the flows controller tubing is connected.
This assosiates the flow controller to a detector.
When CONT. TYPE is WDFID, only heater ports that the DFID is connected to can be
set for piping.
When CONT. TYPE is TCD-L, piping of two units of heater ports need to be set. The
upper line is for the pre heater and the lower line is for the TCD cell. A port that the DFID
(or a pre heater unit without the FID cell) is connected to can be set for the pre heater
and a port that the DTCD is connected to can be set for the TCD cell.
Only heater port that the DFID is connected to is shared for temperature regulation of
the DFID and TCD-L pre heater (set for both).

Current of the detector is abnormal. If the resistance of the filament becomes abnormally
high when the TCD or the FTD is in use, the protection circuit is actuated to prevent damage
to the filament, and an alarm sounds.
If either error has occurred, turn off the system.
Possible reasons for the protection circuit to be activated are described below.
• The set current value exceeds the maximum operating current.
• Gas is not flowing.
• Gas is leaking.
• A significant amount of air is present in the flow line (for TCD).
Correct the error then turn on the system. If the system does not recover after several
resets, or the reason for the error cannot be located, contact your Shimadzu representative.
