I am constructing a dual gas permeation instrument as my senior engineering design project and will be using GC to determine the permeate gas composition. I am new to this technique, so any information, resources, or suggestions are highly appreciated.
We will be using the instrument to investigate the gas barrier properties of polymer films under competing gases (two of the following; H2, O2, N2, CH4, and CO2) in a dual gas mixture. The permeate gas will be fed to a Hewlett Packard G1540A GC.
The gas lines on the instrument must be made of 316/317 stainless steel because of the hydrogen embrittlement caused by the H2 gas. Should I take this effect into consideration for any stage of the GC process?
I am also having difficulties finding a suitable column for separation of the listed gases. Will I need to use two separate columns and is this possible on the GC I have been provided?
Will I be able to conduct all of the necessary analysis with only the TCD that the GC is equipped with?
Thank you for the help!
