Honestly, are portable GCs even used anymore? Were they ever used, and what for?
I found this Portable GC on Ebay
(<-- link) and we have a portable GC in our lab at the University...but it just sits under the sink...I think it got some use a little while ago, stationary, on a desk, because we ran out of REAL GCs lol..
Seems like a crackpot idea to me, what with the gases, calibrant, all that stuff...if anybody has experience / a clue about these, that'd be awesome!
