    Extraction Methods for Hair Samples

    Hair analysis is growing in popularity due to the non-invasive nature of  sample collection. Although not used as routinely as other matrices such as blood or urine it does have advantages in that the matrix can indicate prolonged drug exposure. This can provide valuable information with respect to therapeutic drug regimens or in abused drug abstinence cases.  These application notes describe a simple streamlined workflow for extraction and clean up of hair samples for LC-MS/MS analysis.

    Extraction Methods for Nail Samples

    Human finger (or toe) nail samples may help to provide a more rounded picture of abstinence or abuse and associated timeframes.  These application notes illustrate a streamlined approach to extraction and clean-up of finger nail samples for LC-MS/MS analysis.
