Some of the more labile pesticides in my samples (p,p'-DDT, endrin) are degraded. I assume this is occurring in the inlet, because they still generate discrete peaks, but those peaks don't appear where they belong in the chromatogram. I've used new standard, liner, glass wool, guard column, and even installed a new analytical column, but the problem persists. I'm doing splitless injection, and using a straight-tube liner. What am I missing?
