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
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.

This application note describes the extraction of a broad range of analytes from liver tissue matrix prior to GC/MS analysis using ISOLUTE® SLE+ supported liquid extraction columns.
A protocol has been developed that allows the simultaneous
extraction of various drugs of abuse classes: amphetamines, barbiturates, benzodiazepines, cocaine, ketamine, THC.
In addition to these drug panels, simultaneous extraction of carbamate, organochlorine, organophosphate, pyrethroid, and triazine pesticide classes is demonstrated.

This application note describes a procedure for sample pre-treatment and extraction of THC and metabolites from human hair, using Biotage® Lysera for matrix pulverization of the sample prior to clean up using ISOLUTE® SLE+ supported liquid extraction.
Manual processing protocols were developed using the Biotage® PRESSURE+ 96 (plate format) or 48 (column format) positive pressure manifolds. For automated processing, protocols were developed using Biotage® ExtraheraTM.

Hair is a useful matrix for drug analysis, as it can be used to show historical drug use. Parent drugs are often present in high concentrations, and the matrix is stable over time.
This poster describes the use of the Biotage® Lysera to pulverise and extract hair samples, with ISOLUTE® SLE+ supported liquid extraction columns to clean up the samples prior to analysis. Limits of quantitation set by the Society of Hair Testing for amphetamines are achievable with the described method (0.2 ng/mg).

This poster describes a simple but effective method for screening a range of pesticides and drugs of abuse from liver samples. Liver tissue is homogenized using the Biotage® Lysera, and the subsequent extract is cleaned up using ISOLUTE SLE+ supported liquid extraction columns.
