Cortisol measurement in hair samples scan be a useful indicator of chronic stress. This poster compares a new LC-MS/MS method with an existing immunoassay based method.
The Biotage Bead Ruptor is used effectively for hair pre-treatment.

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.

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 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 application note describes a procedure for sample
pre-treatment and extraction of a panel of 49 drugs of
abuse from human hair, using Biotage® Lysera for matrix
micropulverization, prior to clean up using ISOLUTE® SLE
supported liquid extraction. The application note contains
procedures optimized for 400 μL capacity column format and
200 μL and 400 μL supported liquid extraction plate formats,
for higher throughput applications. The methodology delivers
clean extracts and analyte recoveries mostly greater than
80% with RSDs lower than 10% for all analytes and LLOQ from
