Any ideas as to what could cause a static headspace injection to produce peak areas roughly 60-80% higher than the other injections in the series? For example, in a 6-injection series of a std. solution containing 12 residual solvents, 5 out of the 6 injections will be right on top of each other with %RSDs <5 for all analytes. See more results
