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.
