Determination of Seven Problematic Pesticides in Olive Oil

UCT, Inc.
12 Dec 2014

Recoveries of seven problematic pesticides in olive oil, including six base sensitive compounds and one acid sensitive compound were determined by a modified QuEChERS procedure using GC/MS in SIM mode. Comparisons of different clean-up methods were also evaluated. PSA/C18 dual layer SPE cartridges provided the best extract clean-up.
