I'm trying to develop a terpenes method in a hurry on a system that seems less than ideal for this analysis. I'm coming from an Agilent 7800 with a 7697A headspace sampler which is a pressure loop system. I'm now working on a Thermo TriPlus RSH. This is a static headspace system. I'm having troubles with carryover from the syringe and also high boiling terpenes (bisabolol and guaiol) seem to be getting caught in the syringe. They come out after doing IPA injections following standard injections. I really don't know how to go about improving this. The syringe and agitator oven temps are plenty hot enough. I'm not sure how else to avoid this. For carryover I was thinking I would inject less sample and decrease the split to put the same amount on column but less in the syringe?
Any help is much appreciated.
