Suitable GC for Hydrocarbons Suitable GC for Hydrocarbons oswald88 (Mechanical) (OP) 11 Jan 18 08:19 Dear All I am looking to procure a GC for hydrocarbons from C1 to C8. Suggest a suitable and best ones. Oswald Vincent M.S Mech. Engg. Keep Things Simple. RE: Suitable GC for Hydrocarbons georgeverghese (Chemical) 11 Jan 18 23:00 While I dont have suitable manufacturers to recommend, pls also note that for a GC to work well, I'd say 80% of the required engineering work is in the gas sampling and preconditioning kit, and 20% is in the vendor supplied GC. If not all, most GCs' dont work because gas preconditioning is not adequate.
