Developing New Methods for Pesticides in Dietary Supplements

In this application note a procedure is demonstrated that incorporates a QuEChERS extraction, cSPE cleanup and GCTOFMS, resulting in good recoveries for a wide range of pesticide chemistries in dandelion root powder. This approach saves time and can reduce analyst variation by minimizing manual preparation with prepackaged extraction salts and snap-and-shoot standards. Analytical benefits include reduced interferences and good recoveries, even of polar compounds.
