This application note describes the extraction of 96 licit and illicit drugs of abuse from urine prior to UPLC-MS/MS analysis using EVOLUTE® HYDRO CX 96-well plates.
EVOLUTE® HYDRO CX plates offer an efficient way to perform hydrolysis in the well of the extraction plate. This method provides high analyte recovery, reduced extraction time due to the elimination of a sample transfer step as well as the elimination of the column conditioning and equilibration steps, and a reduced risk for sample carryover or cross-contamination due to the elimination of the sample transfer step.

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.

Pesticides, including insecticides, herbicides and fungicides are used extensively to increase agricultural yields. The total world usage of pesticides in 2007 was approximately 5.2 billion pounds with the US consuming approximately 22% of the total.1 The wide use of pesticides yields concern that drinking water sources will become contaminated, exposing the population to hazardous substances that may cause cancer.

US EPA Method 1664 for Hexane Extractable Material (HEM) or Oil and Grease has allowed use of solid phase extraction (SPE) instead of liquid-liquid extraction (LLE) with hexane since 2007 and this has been widely adopted in the US. SPE is an equivalent extraction technique to LLE and produces the same n-hexane extract. The extract, similar to LLE, may contain residual water that must be treated properly and removed from the n-hexane extract.

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.

Pesticides have gone far in increasing food supply, important in a world expecting to have 9.8 billion people by 2050. However, the mechanisms that make pesticides effective in eliminating pests can also cause harm to humans and animals. News stories continue to point to contamination through spills and exposure through the respiratory system.

Polychlorinated Biphenyls (PCB) are a worldwide contamination problem. They are extremely stable and as such, very long lived in the environment. The end result is that PCBs tend to bioaccumulate throughout the food chain and a great deal of research and regulations have been dedicated to their study.

Argoresin MP-Isocyanate is a macroporous polystyrene-bound scavenger, for nucleophiles such as amines and alkoxides. Resin bound scavengers are added after a reaction is complete in order to quench and react selectively with excess reactants and/or reaction byproducts. The resulting resin-bound reactants are removed by simple filtration.

Argoresin MP-TMT is a macroporous polystyrene-bound trimercaptotriazine,
a resin-bound equivalent of 2,4,6- trimercaptotriazine (TMT). The resin is
designed to scavenge residual palladium from products derived from palladium
catalyzed reactions.1 Despite the widespread use of palladium-mediated
reactions, removal of residual palladium during workup and product isolation remains a major problem. Reducing the palladium content to the low parts per million (ppm) levels, as is required for active pharmaceutical ingredients, is particularly challenging.
