Temperature(Pre) -- Gas Chromatography Question

  1. Dec 1, 2016 #1
    Does anyone here have any experience with GC? I am developing a method for analyses and I understand all the settings but there is one related to the TCD called Temperature(pre). Does anyone have any ideas?

    Thanks for any suggestions!

    Do you have access to the Operator's manual? Maybe google around for the make and model of your GC. Sometimes you can find manuals online.

    Why are you using a thermal conductivity detector? Flame ionization detectors are so much better. To be honest, I've never used TCD or electron capture, FID all the way, or mass spec. Is you analysis specific for TCD?

    Apologies for the late reply. Simply put we have limited experience using the GC and it is already set up for TCD analysis. I'll be using it for analysis of gases such as CO2, CO, H2 and short chained hydrocarbons.

    ^^ The manual mentions noting of the Temp(Pre) unfortunately.
