Pain management therapy warrants constant monitoring of therapeutic levels of prescribed drug levels in patient urine samples. The number of samples being submitted for analysis has increased dramatically in the last 10 years with improvements in high throughput automated screening capabilities. Patient samples analysis is complicated by the need for an effective sample preparation methodology that can extract target analytes from complex matrices with good efficiency. Further complicating the process is the need to enzymatically hydrolyse the glucoronidated metabolites prior to extraction from the urine matrix. A fully automated sample preparation process using a TECAN Freedom EVO® 100 was designed to incorporate both the enzymatic hydrolysis and subsequent sample preparation assay as one continuous workflow. Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) and solid phase extraction (SPE) techniques was used to extract a suite of pain management drugs from spiked urine samples. A recovery and quantitation assay was run on the TECAN Freedom EVO® 100 using mock patient samples to demonstrate utility of automation process.

The ability to extract a broad range of different drugs from a biological matrix allows for the expedited analysis of a patient sample using LC-MS/MS. Typically small molecules are extracted from matrices like urine based on their polarities. A fast and reliable sample preparation method that could be implemented to extract drugs of different polarities from urine could be used as a screening tool to quickly identify the presence of illicit drugs in patient samples using LC-MS-MS.
This poster demonstrates the utility of supported liquid extraction for the extraction of over 30 different acidic, basic and neutral drugs in urine prior to LC-MS/MS.

Solid matrix analysis by LC/MS or GC/MS is generally more involved due to the necessity of multiple manual steps to convert the sample into an extractable form. This poster aims to demonstrate workflow advantages for fingernail analysis; multi-sample homogenization, extraction and analysis for a range of drugs of abuse.

Routine testing for drugs of abuse (DOA) in urine is commonly
performed by many clinical, forensic, and pain management
laboratories. The method of testing varies but can often provide
unwanted load stress for day-to-day operation in labs. Most seek
simplified yet reliable and robust modes of sample preparation and
analysis. ASMS, 2020.

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.

This poster shows an extraction protocol for 12 common drugs of abuse (DOA) to be detected in breast milk using mixed-mode polymeric cation exchange solid phase extraction (SPE).
Using the combination of reliable automation (on Biotage Extrahera) and SPE sample preparation techniques, a method was developed demonstrating the precision, accuracy, linearity, and sensitivity necessary for a robust quantitative workflow.

This poster presents a method for detection of approximately 100 drugs and metabolites in urine using mixed-mode polymeric cation exchange solid phase extraction (SPE).
Four different glucuronidase enzymes and several incubation times and temperatures were evaluated to determine optimum hydrolysis conditions for seven commonly detected glucuronide metabolites. Samples were subjected to offline hydrolysis and SPE (EVOLUTE® EXPRESS CX, Biotage, Charlotte, NC) and results compared to an SPE plate that incorporates in-well hydrolysis (EVOLUTE HYDRO CX, Biotage).

GC/MS is still a mainstay in forensic analysis for drugs of abuse
testing in urine. Historically silica-based solid phase extraction
(SPE) columns have been used for these target analytes, the exact
choice being dependent on drug functionality. This poster aims to compare various sample preparation techniques for this analysis. ASMS, 2020.

Evaporative crosstalk is well-to-well cross contamination
during extract evaporation after SLE or SPE extraction in a 96
well plate. It is often observed with volatile analytes like
methamphetamine and amphetamine, but it can also occur
with other drugs and metabolites when urine samples have
very high analyte concentrations. ASMS, 2020.

This poster demonstrates that a large urine panel, comprised of 43 DOAs, from multiple drug classes, can be simultaneously screened by mixed-mode cation exchange SPE (using EVOLUTE EXPRESS CX 96 well plates) despite their disparate intermolecular traits, by thoughtfully selecting appropriate organic wash and elution conditions that simultaneously enable sample isolation and detection along with minimizing sample matrix effects.
The extraction method is automated using the Biotage® Extrahera™ Automated sample Preparation Platform.

Miniaturisation within various fields of analytical chemistry is not a
new phenomenon. Early phase small animal drug trials have largely
been the driver due to limited sample sizes available. However, this
trend is gaining popularity in forensic/clinical toxicology with
respect to alleviating patient discomfort, particularly in paediatrics.
Increased LC-MS/MS sensitivity has reignited this focus area. This
poster will evaluate a novel low-volume 96-well solid phase
extraction (SPE) format and potential application to forensic and
clinical toxicology. ASMS, 2020.
