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.

This application note demonstrates the use of automated solid phase extraction for a variety of pharmaceutical compounds in drinking water,
wastewater and surface water. The criteria specified in US EPA Method 1694 was met, even at very low concentrations. For lower concentrations a larger sample of water may be processed.

Throughout the world, a lack of regulation has been blamed for the detection of pharmaceuticals and personal care products (PPCP) in some bodies of water. While the detected amounts are usually relatively small, the persistence of these compounds means that they can cause untold damage to the ecosystem for years to come.

EVOLUTE® EXPRESS SPE columns and plates combine sorbent wettability with optimized SPE components, allowing better flow consistency and in many cases eliminating the need for SPE column conditioning; thus simplifying and reducing extraction processing. This poster compares the performance of various EVOLUTE EXPRESS column chemistries using 10-500 mg bed weights, in order to investigate whether sorbent conditioning and equilibration steps are truly required.

Most drugs are excreted in urine as glucuronide conjugates. Hydrolysis using a beta-glucuronidase enzyme to convert the metabolites to their “free” form for analysis increases sensitivity. Red abalone (Kura Biotech), abalone (Campbell Scientific), and recombinant (IMCSzyme) beta-glucuronidase enzymes were evaluated to determine which provided the most complete hydrolysis of glucuronide metabolites without effecting the overall recovery of non-conjugated compounds.
EVOLUTE EXPRESS CX 96-well plates were used to extract hydrolysed urine samples, and the impact of th enzymes was compared.

Sample preparation is generally regarded as a pain point for many labs as it can be laborious, time consuming and relatively expensive. In a high throughput setting performing offline chemistry also leads to increases in sample turnaround time and reporting.
This poster evaluates simplified sample preparation workflows using optimized sample hold-up technology allowing chemistry in-situ. Reduced labour, extraction complexity, processing time, solvent usage and resultant instrument contamination and downtime can offset upfront costs associated with sample preparation.

This application note describes the extraction of 47 drugs of abuse and metabolites from oral fluid matrix collected using the Intercept Oral Fluid Drug Test Kit (Orasure Technologies), prior to UPLC-MS/MS analysis. The sample preparation is optimised to minimise matrix effects due to the buffers used in the collection device. Estimated LOQs range from 0.1-1 ng/mL for the various analytes.

This application note describes the extraction of 47 drugs
of abuse and metabolites from oral fluid matrix after sampling via Oral-Eze collection devices, prior to UPLC-MS/MS analysis using ISOLUTE SLE+ supported liquid extraction columns. Estimated LOQs of between 0.005 and 0.75 ng/mL (analyte dependant) are achieved,.
