24 May 2012

Read this application note to learn more about a method for an accurate, reliable and robust method for quantifying cannabinoid compounds in biological samples. THC - COOH is monitored in urine because it allows for a longer window of detection and thus can be used as a marker of consumption due to previous Cannabis use. The Xevo TQ MS meets the sensitivity requirement and the ACQUITY UPLC separation method allow for high sample throughput for analysis of THC-COOH.
