| A GC-MSn analytical method was developed using an external ionization ion source ion trap mass spectrometer to provide a robust and sensitive analysis of over 45 pesticides in a food oil extract.
The time savings created by the use of a back-flush on the PTV injection port to prevent late-eluting triglycerides from entering the analytical column was demonstrated in a reduction of run time from 45 to 35 minutes. In addition, required maintenance was minimized since less matrix entered the analytical column and mass spectrometer. Both of these reduce the analysis cost.
For over 700 injections, the ion volume was cleaned only once and the injection port liner was replaced once. The injection port septum was replaced every 50 injections.
