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.

Part No: AN855Issued year: 2015File size: 1mbFile type: pdf
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).

This application note describes the extraction of a range of amphetamines and metabolites from urine using supported liquid extraction and subsequent analysis by GC/MS. Prior to extraction, a simple oxidation step is performed to eliminate sympathomimetic compounds such as ephedrine and pseudoephedrine so they do not interfere with quantitation of methamphetamine.

Testing for drugs of abuse in oral fluids can strongly benefit the criminal justice field as a less invasive and cost-effective approach for drug detection when compared to blood or urine sampling. Oral fluid analysis has facilitated laboratory analysis for many drugs of abuse and is a constantly evolving analysis procedure which benefits from increasingly sensitive methods of detection. The Laser Diode Thermal Desorption (LDTD) source combined with Mass spectrometry is presented as a new screening tool for drug analysis in Oral Fluids. Analysis speed of LDTD provides accurate results in seconds in combination with exceptional specificity of MS instruments make a powerful platform for the screening of different drugs of abuse and new emerging drugs. Different extraction procedures are available; however those methods depend on specific drug conditions: basic or acid drugs / hydrophilic or hydrophobic. A new extraction approach, Supported Liquid Extraction (SLE+) is evaluated as generic extraction procedure.
