The SDT Q600 is an instrument capable of making two different thermal analysis measurements
simultaneously on the same sample. Depending on which operational mode is used, these
measurements are heat flow (DSC) and weight change (TGA) or differential thermal analysis
(DTA) and weight change (TGA). Simultaneous measurement of two properties not only
improves productivity but also simplifies interpretation of results. The information provided
allows differentiation between thermal events that have no associated weight change (e.g.,
melting, phase change) and those which involve a weight change (e.g., decomposition).
NOTE: Please come to discuss with the MCL staff before you starts to use a
new sample material in this instrument. All the physical and chemical
properties of this new sample material must be reviewed and discussed!!!
Electrical Safety
You must unplug the instrument before doing any maintenance or repair work. Voltages
exceeding 120 volts AC are present in this system. If you are not trained in electrical
procedures, do not remove the cabinet covers unless specifically instructed to do so in
the manual.
After transport or storage in humid conditions, this equipment could fail to meet all the
safety requirements of the safety standards. The equipment needs to be dried out
before use.
Chemical Safety
Use only the purge gases listed in manual. Use of other gases could cause damage to the
instrument or injury to the operator.
Do not use hydrogen or any corrosive or flammable gases in the SDT furnace. Air can be
used as a purge gas in the SDT. However, the furnace must be kept clean of volatile
hydrocarbons that might combust.
The SDT furnace assembly contains a layer of refractory ceramic fiber (RCF) insulation.
This insulation is completely encapsulated within the furnace can, which is not meant to
be disassembled.
If you are using samples that may emit harmful gases, vent the gases by placing the SDT
near an exhaust.

After running an experiment, allow the open furnace and sample beams to cool down
before you touch them.
During a sample run, the furnace can be hot enough to burn skin. Avoid contact with the
furnace during experiments.
Mechanical Safety
Keep your fingers and all other objects out of the path of the furnace when it is moving.
The furnace seal is very tight.
The SDT is a fairly heavy instrument. In order to avoid injury, particularly to the back,
please use two people to lift and/or carry the instrument. The instrument is too heavy
for one person to handle safely.
