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.

Over the past decade, the need for non-invasive drug screening that that precludes sample adulteration has become attractive. As a result, detection using oral fluid devices for Drugs of Abuse (DOA) has come to the vanguard of the scientific community. The use of Supported Liquid Extraction (ISOLUTE® SLE+) prior to LC/MS or GC/MS can improve sample cleanliness without forfeiting sample detection within a diverse panel of DOAs. Here, we demonstrate the effects of altering elution solvent polarity and pH for sample pretreatment upon the simultaneous recovery of 34 compounds comprised of opioids, benzodiazepines, and stimulants to directly measure the effects of the oral fluid buffer, OraSure™, upon extraction and signal intensity at presumed LOQs.

In postmortem cases, where drugs or pesticides have been used for
their poisonous properties, traditional matrices such as urine and
whole blood may be inappropriate for qualitative and quantitative
analysis. As the site of metabolism for most drugs and toxins, the
liver may provide more insight to cause of death than other bodily
fluids.
This poster describes the use of ISOLUTE SLE+ supported liquid extraction columns to extract a range of drug and pesticide classes form homogenised liver using a simple, streamlined workflow.

Benzodiazepines are psychoactive drugs used to treat various conditions including anxiety, insomnia, seizures and alcohol withdrawal. Long-term use can cause physical dependence and withdrawal upon cessation of use, due to this their application as medication has to be monitored and measured. This application note details an optimized extraction protocol for the use of ISOLUTE SLE+ supported liquid extraction plates (96-well) and 1 mL sample volume columns to extract a range of benzodiazepines from human urine. This simplified and efficient extraction method has analyte recoveries from 85% with LOQs as low as 100 pg/mL.
