Ferrules are typically used in the
hot sealing of columns, inlets and detectors, and they can also be used for gas
connections. Ferrules are made of graphite, Vespelâ„¢, metal and PTFE materials.
Available in ¼ and 1/8 OD to fit Nut and in different sizes of internal
diameter
Fittings
can provide reliable high-pressure sealing. We use Swagelok fittings with front
and back ferrules which give best sealing performance throughout all our GC
systems. We also provide customers fitting in different sizes and materials.
Gas Purifier
can help deliver high purity gas to your analytical instruments, to extend
column lifetime and reduce instrument downtime and improve efficiency. Helps to
remove CO2, oxygen, moisture, and hydrocarbons from carrier gas. The purifier
can work with the GC, GC/MS and any other analytical instrument using carrier
gas.
Gas sampling valves are used to sample gases in constantly flowing
streams. For more challenging valve applications, such as natural gas or
transformer oil gas analysis, we can also offer preconfigured analyzers with
valve sampling to customers.
Glass-made
GC inlet liners provide chambers sample vaporizing and sample introduction into
the column. Liners are the centerpieces of the inlet system and have a direct
impact on application reliability and accuracy. Liners come in different lengths, diameters (OD/IDs), shapes, and
surface deactivation for different instruments, sampling and applications
Gold
seals form a leak-free seal with the bottom of the inlet body and column
ferrule to minimize both sample contamination and sample loss. Our gold seals are made with a metal injection molding process
that provides a consistent, smooth surface, free from ridges or grooves from a
machining process. For convenience, the gold seals are carefully
packaged with inlet seal washers.
Silicone-based
septa are typically used for both GC inlet seals and sample introduction. They
have a centered hole for guiding the syringe needle. Quality and performance of
septa have a direct effect on application results (reliability and accuracy),
column lifetime and instrument condition. A good practice is to check and
change septa as often as needed.
We
offer inline gas filter that can remove common contaminates such as oxygen,
moisture, and hydrocarbons from GC carrier and detector gases. Our inline gas
filters are available in different sizes and configurations.
Syringes
are generally use for volume injections. Different brands of autosampler use different needle lengths and
plunge headers. Larger volume syringes can be for special autosamplers such as
CTC or large gas sample injections. GS-Tek offers a broad range of microliter
syringes for several autosampler brands
GS-Tek
offers a variety of pre-cleaned tubing for gas line connections. Tubing
materials are aluminum, Fused Silica, 304SS, Ni, copper, Al, stainless steel
and PTFE.
