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

A robust analysis method for steroids was developed that can readily be implemented by clinical, forensic, or anti-doping laboratories.

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

This application note introduces a simple targeted extraction method for the analysis of nine nitazene compounds from urine and blood using the Clean Screen® DAU column.

A simple and robust method for the analysis of Opioids in biological matrices using UCT's Clean Screen® DAU SPE column and Selectra® DA UHPLC column.

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. 

This note reviews the process of extraction of synthetic and naturally occurring cannabinoids in urine using SPE and LC–MS/MS using UCT’s SSHLD extraction cartridge.

Reviews the highly retentive but universal nature of UCT’s polymeric Styre Screen® HLD sorbent for analysis of barbiturates, benzodiazepines, and THC in oral fluid.

A simple and robust method for the detection of 16 cannabinoids in hemp and cannabis samples using a rugged isocratic HPLC method coupled with UV detection.

A solid-phase extraction method utilized to extract 19 synthetic cannabinoids produced recoveries in the range of 85–110% with corresponding RSD values of less than 5%.
