I am looking to set up in line sampling on a GC/FID (6850A, G2630A) with a capillary column. I have found sample valves listed for 6850 series GCs (e.g. G2668A), but the part description specifies it is for G2630B, so I take it that this is incompatible with our GC. Is there a way to adapt it for usage on a G2630A, or is there an equivalent part for this model?
