• If your TSQ 8000 system will be equipped with a Direct Insertion Probe, make sure you
have compressed air, which is used to cool the probe.
• If you have a TriPlus autosampler with the SPME conditioning station or a TriPlus
Headspace autosampler, you need to obtain a low-pressure, single-stage regulator
(0-30 psi) for nitrogen purging.
• Gas lines should be:
– As short as possible and close to the TSQ 8000 system.
– Made of copper or stainless steel when using helium, hydrogen, methane or
isobutane.
– Made of stainless steel when using ammonia or other corrosive gases.
– Free of oil and moisture
• Obtain the proper gas line filters, which help prevent impurities and contaminants from
entering your system. Water, oxygen, and total hydrocarbons should be less than 1 ppm
to avoid high background noise and prevent contamination. The GC is equipped with
two intake filters that trap moisture, oxygen, and hydrocarbons.
• Store gas tanks and bottles properly so they will not damage cables or gas lines. Ensure
they are secured in accordance with standard safety practices.
CAUTION
If your TRACE 1300/TRACE 1310 and PTV injector will be equipped with a
cryogenic cooling option, see the TRACE 1300 and TRACE 1310 Preinstallation
Requirements Guide for more information.
