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.

Hair analysis is growing in popularity due to the non-invasive nature of the sample collection. Although not used as routinely as other matrices such as blood or urine it does have advantages in that the matrix can indicate prolonged drug exposure. NCFM 2020, Reykjavik, Iceland

Sample preparation for hair analysis is often lengthy involving multiple manual labor steps from cutting, washing, homogenization/pulverization, digestion, sample extraction and analysis. This poster aims to demonstrate a streamlined sample
preparation workflow for hair analysis.
The workflow is evaluated using a suite of drugs of abuse, including THC and metabolites.

This application note describes the extraction of a range of amphetamine-type compounds from whole blood, prior to GC/MS analysis. A protocol that allows the simultaneous extraction of various other drugs of abuse classes: barbiturates, benzodiazepines, cocaine and opiates, is also evaluated.
ISOLUTE® SLE+ columns with 1 mL sample capacity are used to extract whole blood samples following a straightforward sample dilution. No protein precipitation or other pre-treatment is required prior to sample loading. The sample preparation procedure delivers clean extracts, good recoveries and RSD values and LLOQs from 10 ng/mL (analyte dependant).

‘Bath salts’ is the street name for a family of designer drugs chemically similar to cathinones that give the user similar effects to amphetamines. The abuse of these drugs is on the increase and regulation against their use and supply has now been implemented in the EU and North America. Analyte recoveries achieved using this method to extract bath salts from urine ranged from 87-99% with RSDs below 10% for all analytes.

Mephedrone (MCAT) is a ‘designer drug’ synthesised to mimic the amphetamine class of compounds. Due to its perceived ‘ecstasy like’ effects of euphoria, excitement and alertness combined with ease of availability, this (until recently) unregulated drug (legal high) has found widespread abuse in the UK in recent years. Harmful effects associated with mephedrone are still being studied but after several deaths were linked to the abuse of the drug, the UK Government made this a Class B substance. Mephedrone extraction was evaluated on three mixed mode cation exchange SPE sorbents: EVOLUTE® CX, EVOLUTE® WCX and ISOLUTE® HCX.

Dilute and shoot (D/S) is the most common form of sample preparation for the high throughput analysis of drugs of abuse (DoA)in urine. Although superior in extract cleanliness, solid phase extraction is sometimes deemed too complex, expensive and time consuming especially when matrix hydrolysis is required. This poster aims to demonstrate a simplified sample preparation workflow utilizing on-plate urine hydrolysis, organic solvent precipitation followed by flow through filtration and matrix component scavenging.
