GC sampling under vacuum
GC sampling under vacuum
(OP)
Hello:
I am trying to build a membrane based bench-top lab scale facility for measuring gas permeabilities and selectivities for mixed gases (90vol% CH4-10%CO2) by keeping permeate side under vacuum. I intend to analyze these gases at permeate side by GC. Since it will be under vacuum, I am wondering how should I do. I need to take a gas sample and then inject it in GC machine. Will someone help me about taking the GC sample from the system under vacuum. Thanks.

Are sampling syringes applicable ?

I feel it is better to make one inhouse.
