Analysis of drug panels in urine samples can be challenging, and the trend towards larger panels including multiple drug classes compounds the issues faced during method development.
This white paper examines a number of aspects of sample preparation, and their impact on the success of subsequent LC-MS/MS analysis of broad urine panels.
Section 1 examines the applicability of various sample preparation techniques: supported liquid extraction, reverse phase SPE and mixed-mode SPE, to the various classes of drugs extracted. In addition, hydrolysis approaches: enzyme type and protocol used (time, temperature), are compared.
Mixed-mode reverse phase/cation exchange SPE is widely used for extraction of basic drug classes from urine, but the inclusion of drugs and metabolites that exhibit ‘non-typical’ functionality within urine panels can be problematic. Section 2 examines the impact of various parameters (interference wash strength, elution solvent composition) on analyte retention, elution and extract cleanliness with particular focus on zwitterionic (gabapentin, pregabalin) and non-ionic (carisoprodol, meprobamate) drugs.

Designed polymers are a class of selective resins with engineered selectivities for particular target molecules or ‘classes’ of molecules. These designed polymers are obtained by careful tuning of their surface chemistry and morphology which allows them to exhibit unique separation capabilities. The tailored and optimized selectivity of designed polymers is utilized to conduct difficult separations that are not able to be accomplished with conventional separation resins or other techniques.

Deoxynivalenol is a common mycotoxin found in agricultural grain crops and final consumer processed products. Most impacted are wheat, barley, and corn. Deoxynivalenol, also known as Vomitoxin, is produced by Fusarium fungi and has a unique dual-stage growth cycle of producing mold during warm daylight and toxin during cool nights. There is no known procedure or processing that will remove deoxynivalenol that is already present in grain.

Hormones in drinking water are a growing concern, since the presence of these compounds can potentially be linked to serious health hazards such as human developmental and reproductive side-effects. Hormones are introduced into our environment in several ways. Natural and synthetic hormones that are given to livestock, pass though the animals, runoff into surface water, and leach into underground water supplies. Humans also produce and excrete natural hormone waste every day.

The second Unregulated Contaminant Monitoring Regulation (UCMR2) program was developed to monitor US drinking water sources for currently unregulated compounds. EPA Method 529 is categorized under List 1, Assessment Monitoring in the UCMR2 program, and focuses on three explosives: 1,3-dinitrobenzene; 2,4,6- trinitrotoluene (TNT); and hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX). The resulting data will be used by the EPA to determine whether or not regulatory standards should be established for these compounds.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants, naturally occurring in coal, crude oil, gasoline, and their byproducts (e.g. coal tar or creosote). In addition, PAHs are formed in the incomplete combustion processes of all organic materials, such as wood or fossil fuels. Consequently, the EU water framework directive (WFD) lists in its annex X the whole group of PAHs as priority hazardous substances.

The formation of diarylethers by reacting an arylhalide and phenol is usually a reaction demanding long reaction times, high temperatures and strong bases, in order to obtain acceptable yield. The substitution patent of the electrophile and the nucleophile affects the reaction times mostly. A sterically hindered electrophile and a strongly deactivated nucleophile as outlined in the (Scheme 1) below, gives a very low yield (13 %) at conventional reflux for 2 weeks.1,2 Remainder was
recovered starting material. We have previously reported the dramatically shortened reaction time to 1 hour along with improved yield running the reaction outlined in the Scheme by heating by microwaves.
