Hi. I have work with normal split/splitness injector for liquid product. Then later with gas valve sampling system for gas products with reactor. My colleague told me now that we should think about upgrading our GC by having an all online (valve) GC system for our reactor. I don't know how to acheive that, since we are dealing with high boiling point compound, ie. 280C...coz when we cannot have a product line from the reactor always at above 300C!

Maybe it is due to my inexperience, but are there any applications that allow online-GC that can deal with liquid?

Liquid sampling is quite trivial and common in the process control industry. Certain safety precautions must be implemented, of course. Heat transfer, valve seal material integrity, proper filtering of sample, and return of sample to reactor or disposal are considerations that must be addressed before the pool of liquid collects on the floor.

Valco or some other manufacturer may offer suggestions and direction.
