Application Note: Determining Pesticides in Dietary Supplements with QuEChERS Extraction, Cartridge SPE, and GCxGC-TOFMS
1 April 2011

In this application note a novel approach is employed combining QuEChERS extraction, cartridge SPE cleanup, and GCxGC-TOFMS analysis to quantify pesticides in dietary supplements. It results in good recoveries across a range of compounds found in these complex matrices and reduces matrix interferences and improves accuracy relative to one dimensional GC-TOFMS.
