Abstract The Stakeholder Panel on Infant Formula and Adult Nutritionals met during the AOAC Annual Meeting held September 30 to October 3, 2012 in Las Vegas, NV, to review data submitted for a method, pantothenic acid (Vitamin B5) in infant formula and adult/pediatric nutritional formula by ultra-performance LC (UPLC)-MS/MS. The method uses a simple sample preparation with chromatographic analysis by UPLC-MS/MS with positive electrospray ionization.

Abstract In this rapid TLC method of analysis for the urinary cannabinoid metabolite, 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), hydrolyzed urine specimens are aspirated through a porous, alkyl-silica extraction layer located along the lower edge of a biphasic thin-layer chromatogram; THC-COOH is simultaneously extracted from the sample and concentrated on the TLC plate for subsequent migration and detection. The method, evaluated in a blind study, identified all samples containing THC-COOH greater than or equal to 20 micrograms/L. The technique increases samples throughput, sensitivity, and specificity as compared with conventional TLC methods and is applicable to a wide variety of compounds.
