Can the inlet liner help reduce baseline noise?
Can the inlet liner extend the lifetime of my GC column?
How often should I change my inlet liner?
Can the inlet liner reduce peak tailing?
What are the benefits of using an SGE OptChem bottom taper inlet liner with glass frit?
Can I download these inlet liner questions and answers?
GC ferrules
What materials are available for GC ferrules?
Can I use graphite ferrules on my mass spectrometer connection?
Is 400°C really the maximum temperature for 100% graphite ferules?
What pressure is suitable for ferrules 072621 and 072622 100% graphite ferrules?
Can SilTite ferrules be used with aluminium clad columns?
Are there SilTite connections for the Thermo injector?
Which SilTite kit should be used with the Thermo ISQ?
Can SilTite ferrules be used with the normal nuts that I use with my graphite vespel ferrules?
Which way does the SilTite ferrule go into the nut?
SilTite FingerTite
The first dimension of our GCxGC system is stainless steel capillary column. Can I use SilTite μ-union for column connection?
GC septa
Do any of the current range of GC septa have a PTFE lining?
What is the thickness of your GC septa?
Do GC septa contain phthalates that can contaminate my analysis?
What type of CRS GC septa are equivalent to Trajan GC septa?
What is the tube insertion depth?
What is the ID of the 1.1 mm OD tubing used for SilFlow (part number 123755)?
How do I remove ferrrules sticking in SilFlow?
How do I remove pieces of column broken off in my SilFlow?
Can I put my SilFlow in an ultrasonic bath?
What temperature can I heat my SilFlow up to?
Gas purifiers and filters
What type of CRS gas filters are equivalent to Trajan Big Traps?
What is the difference between a purifier, a filter, and a trap in the CRS product line?
Should I mount them horizontally or vertically?
Should I use brass or stainless steel fittings?
How long will my filter or purifier last?

What are the minimum and maximum operating temperatures for the gas and vapor sampling kit?
Micro Control Valves
What is the Internal volume of MOVP part number 1236091?
My SMOV valve part number 1236282 has a PEEK seat. Is a vespel seat available?

What is the phase used for the CYDEX-B columns?
What is the standard length of SilGuard guard columns?
Do you manufacture packed columns?
How do I condition my capillary column before using it?
Do you supply bonded phases for your capillary columns?
