I have a HP5890 GC. It works well when I use the TCD of GC to detect the Argon/N2 mixture with Helium as carrying gas.
Recently, I need to find out the Helium-3 in a tank. Is it possible that my current setup of my GC would work to find out Helium-3? In my understanding, I might need to switch the carrying gas to avoid Helium 4. But I found a paper, it was about detecting Helium-3/Hydrogen mixture with Helium-4 carrier gas. So, I got confused now.
It is very hard to find paper about detecting Helium-3 with TCD. Can someone give me some idea? I would really appreciate it!
