Traditional Deactivation
Traditionally, liners have only been passivated
with thin deactivation layers – and sometimes
have not at all – putting your analytes at risk of
adsorption or degradation!

What’s A Z-Liner?
Zebron PLUS liners with a Z-Liner geometry contain optimally-placed deactivated quartz wool, which is held in
place by two tapered sections of glass inside the liner. This ensures that the wool remains in the correct position
for injection, wipes the needle tip completely clean, and properly volatilizes the sample.

Fronting Peaks
Symmetrical Fronting
Fronting peaks can occur when the expanded sample exceeds the
liner’s volume. Reducing your injection volume, increasing split,
using a liner with a larger volume, or using a solvent with lower
expansion volume can remedy this issue.
Ghost Peaks
Septum bleed or cored septum fragments lodged in the liner can
cause ghost peaks. Replacing the inlet liner or quartz wool can help
to alleviate this problem. Be sure you are also using the correct
septum that is temperature-rated for your analysis.
Tailing Peaks
Contamination or active compounds can cause tailing. Replacing
your liner can help to reduce inlet contamination and activity;
ensure you are routinely maintaining the inlet for the best
performance. If using a liner with wool, try switching to a liner
without wool if your sample allows.
Split Peaks
When samples do not vaporize in a single location, split peaks may
occur. Try using a liner with wool positioned in the middle of the
liner to minimize split peaks.
Reproducibility Issues
If your liner contains wool, the wool may shift or become dislodged
due to injection or pressure changes, resulting in irreproducible
results. Using a Zebron™ PLUS liner with a Z-Liner™ geometry will
prevent this shifting and improve reproducibility.
www.phenomenex.com/TroubleGC
A The inlet is the most common place where problems happen in GC. This is because:
• The inlet is subjected to very high temperatures.
• There are multiple consumables involved in the inlet that need routine maintenance.
• Some inlet modes, such as splitless injection, result in a slow process which means that
target analytes and the inlet are able to interact with each other for some time before
the sample enters the column.
When dealing with active analytes, a highly deactivated inlet is necessary to minimize prob-
lems that can occur in the inlet, such as asymmetric peak shape and adsorption of target
analytes. Zebron™ PLUS liners are rigorously deactivated and tested for activity to ensure
reliable results when working with highly active compounds.
A Liners should not be packed or re-packed. When attempts are made to remove wool from
the liner or re-pack them with new wool, scratches in the deactivation layer can be created.
When wool is forcefully inserted or removed, these scratches can expose active sites, caus-
ing peak tailing and poor reproducibility.
A No. It is not recommended to scrub/sonicate your liners. Residue formation indicates con-
tamination. More specifically, this indicates that the sample contains non-volatile impurities.
In such cases, it is recommended to replace, rather than clean, your liner. Sonication in sol-
vent can alter the liner’s deactivation and scrubbing can create scratches and active sites.
Both will result in chromatographic problems including and not limited to poor quantitation,
analyte breakdown, poor reproducibility, and peak asymmetry.
A The color of the liner does not determine its inertness. In fact, varying colors can be easily
added to liners by using metal salts during manufacturing. The inertness of the liner stems
from the deactivation process that the liner undergoes, rather than its color alone.
A It is important to periodically check and maintain your liner. The frequency at which a liner
must be changed can be hard to predict as it is entirely dependent on the sample matrix. In
general, if you are performing a headspace injection, only the vapors enter the GC inlet so
the liner will remain clean for months. However, with a neat matrix injection, it is necessary
to check the liner at least twice a week to make sure that it is free of residues. Once a visible
residue is noticed, it is time to change the liner.
Q7 I am using an inert column for my analysis and I still see peak tailing.
What could be the reason for this?
A For analysis of active compounds, it is extremely important to use both a highly inert column
and a highly inert liner. The liner is the first place of potential analyte interaction during GC
analysis, and it is important that your analytes are not adsorbed. Zebron PLUS liners undergo
a rigorous deactivation process and are tested for inertness to ensure reliable results when
working with highly active compounds such as underivatized acids and active bases.
