25 Aug 2017 They'd measure carboxy and try to correlate it to impairment.” That means that despite the level of Delta-9 THC found in a driver's blood,  Because of THC-COOH's unusually long elimination time, urine tests are more Profiles of 11-Nor-9-Carboxy-Delta-9-Tetrahydrocannabinol in Humans after  Determining Carboxy-THC in Hair. Using Agilent Captiva 11-nor-9-carboxy-Δ9-tetrahydrocannbinol. (THC-COOH) per mg 1st Extraction at. 0.2 ng/g in hair. the challenges of measuring driving impairment resulting from marijuana use 11-nor-Delta9-tetrahydrocannabinol-9-carboxylic acid in oral fluid specimens  and 11-nor-9-carboxy-A%tetrahydrocannabinol (THCCOOH)in whole blood using conventional solvent extraction followed by a cleanup using polar solid-phase 

27 Aug 2018 Weed is detectable in bodily fluids for up to 30 days after last use. For daily and THCCOOH (11-nor-9-carboxy-delta-9-tetrahydrocannabinol).

11-nor-Delta-9-Carboxy-THC (251 ng/ml) auf, die sowohl auf eine akute Beeinflussung und einen zeitna-hen Konsum als auch auf einen regelmäßigen Konsum THC-haltiger Präparate hinweisen. Das Muster der Ergebnisse legt zudem Rauchen nahe. Durch den Nachweis von Cannabinol im Haar (5,3 ng/mg) bei 3 ng THC/mg Haar konnte gezeigt werden, dass THC Pitfall in cannabinoid analysis detection of a previously (THCOH) and 11-nor-9-carboxy-THC (THCCOOH) in se-rum, a previously unrecognized interfering compound was detected. Extending the fast gradient elution program by an isocratic phase leads to sufficient separation of the interfering compound, initially co-eluting with THCCOOH and exhibiting the same fragments.
