This application note outlines an extraction method for four natural cannabinoids and the two major metabolites of Δ9-THC in blood using Clean Screen® THC SPE column.

This application note features a unique, simple, and robust solid-phase extraction method for cannabinoids in urine followed by analysis by LC–MS/MS.

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.

This note summarises a procedure developed by the US Food and Drug Administration to measure 16 PFAS in food using a QuEChERS sample preparation approach and LC–MS/MS analysis.  

This application note outlines the analysis of PFAS in drinking water according to EPA 533 using UCT’s Enviro-Clean® polymeric weak-anion exchange (WAX)SPE cartridges.
