Does anyone know if nitrogen can be used as carrier gas in replacement of Helium or Hydrogen?
In fact, I just arrived in a lab, and I have to work on a GC-MS (3800-Saturn 2200) that has been off for years. Since we can't get helium and are not able to work with hidrogen, I'm trying to use nitrogen as the carrier gas, but I get a very bad mass resolution, and I wonder if it's because of nitrogen use or a leak on GC...
Thank you for your answer!
