inorganic gas concentration measurement

I am going to measure the concentration of nitrogen, hydrogen, carbon dioxide and oxygen  gas in the headspace of my bottle and we have agilent GC-MS in our lab (7890B GC- 5977A) MSD). Is it possible with this equipment and what columns and standards are needed? Thank you so much.

  • ISH is correct.  Easier to do this analysis with TCD.  You may be able to add the necessary parts to the existing GC, but it may be easier to get a new analyzer setup to perform this analysis.

  • Dear ISH, 

    Thank you so much. I found a work used PLOT column for this application. What columns do you think are suitable for this?

  • Dear Lance,

    Thank you so much. So, should I connect the existing GC to tcd?
