This poster describes an improved workflow for the analysis of
drugs of abuse from hair. Implementation of bead homogenization along with automated sample preparation allowed for simplified methodology. The direct solvent extraction approach avoids the need for pre-concentration while maintaining desired LOQs with either 200 or
400 μL of hair extract.

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 examines the use of ISOLUTE SLE+ columns as an alternative to SPE for the extraction and clean up of hair samples containing drugs of abuse. SLE was found to be a simple, faster alternative to SPE for this type of analysis.
