Exceptional Recoveries of Planar Pesticides from Spinach and Fresh Oregano - Applications Note

Recently a “Quick, Easy, Cheap, Effective, Rugged, and Safe” (QuEChERS) cleanup method has been developed with the use of Supel QuE Verde, a sorbent combination containing an improved graphitized carbon black (GCB), Z-Sep+, and primary-secondary amine (PSA). This sorbent combination has been shown to provide improved recovery of planar pesticides over current QuEChERS sorbents while maintaining sufficient color removal in high chlorophyll matrices. The GC/MS analysis of select planar pesticides from spinach and oregano extracts is described herein.
