We demonstrate a highly efficient method to monitor Persistent Organic Pollutants (POPs) and separate them from matrix. Common method of analysis utilizes a GC-HRMS or a GC-MS/MS to accurately quantitate and separate toxic dioxins and furans.

Detection and recovery of 268 multi-pesticide compounds using a robust and reliable analytical method ensure consumers' safety according to regulatory standards.

We demonstrate fast PCB analysis using a single GC column as a way to prevent switching from multiple columns and help reduce instrument down time during PCB analysis.

Spinach and other highly pigmented vegetables contain chlorophylls, carotenoids, xanthophylls, and anthocyanins. Chlorophylls have the greatest adverse effect on gas chromatography systems due to their non-volatile characteristics. This QuEChERS procedure uses ChloroFiltr to significantly reduce chlorophylls without sacrificing the recoveries of planar pesticides.
