Sample preparation with the AC Extraction Plate: extraction of urinary THC metabolites for LC-MSMS quantification
Application Note Mar 12, 2014
Tecan Group Ltd.
The metabolite THC-COOH was successfully determined from urine matrix by a combination of AC Extraction Plate for sample preparation followed by LC-MSMS quantification. The range of THC-COOH calibrator concentrations covered the forensically relevant range.
The AC Extraction Plate featuring TICE technology is a fast and easy-to-automate sample preparation method requiring minimal sample pre-treatment. No time consuming or rather costly to automate procedures – such as protein precipitation with centrifugation, filtration or evaporation – are needed thus accelerating and simplifying the entire workflow.
This application note describes a novel sample preparation method for the extraction of THC-COOH from urine for subsequent LC-MSMS analysis, based on Tecan Immobilized Coating Extraction (TICE™) technology.
