Inquiry (采购产品): 310 GC We have had 2 of the series 310 GCs for about 5 years and we have progressively been having problems with separation. Is there a technician who can come out and diagnose our problems? If so, what is the cost? Also, is it possible to convert these GCs to using carrier gases? Thanks for your help.
