Catecholamines and Metanephrines were analyzed using a LCMS-8060 triple quadrupole mass spectrometer. Calibrators were prepared in synthetic urine and extracted using solid phase extraction. Extractions were performed using weak cation exchange on the EVOLUTE® EXPRESS WCX 10 mg 96-well plate from Biotage.

Most drugs, both licit and illicit, are excreted in urine as glucuronide conjugates. Hydrolysis using beta-glucuronidase converts the glucuronidated metabolites back to their “free” or non-conjugated
form, increasing sensitivity for LC-MS/MS analysis. Hydrolysis using red abalone, abalone, and recombinant beta-glucuronidase enzymes was evaluated using an in-well hydrolysis plate to determine which provided the most efficient hydrolysis of glucuronide metabolites without affecting overall recovery of nonconjugated compounds. A glucuronide control containing 8 glucuronide compounds was used to determine the extent of hydrolysis that occurred. A non-conjugated control containing 96 licit and illicit drugs of abuse was evaluated to determine if signal suppression occurred as a result of enzyme hydrolysis.

Analysis of the perfluorinated alkyl acids listed in EPA Method 537 along with fluorotelomeric alcohols and perfluorinated sulfonates were extracted using SPE (using ISOLUTE 101 500 mg/ 6 mL SDVB SPE columns) and analyzed on the LCMS 8045. Minimum Detection Limits(MDL) ranged from 0.69 to 3.25 ppt. Extraction recoveries were greater than 80% for all compounds, with surrogate recoveries within 10% of the true value.
