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.THC in hair
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.THC in nails

Supported Liquid Extraction (SLE) is a sample preparation technique that has been in use for over ten years now, but many analytical chemists don’t know about, or understand the best way to do an SLE extraction. In this post, I’m going to talk about how SLE works and the proper way to do an SLE extraction for sample clean up.
Method development chart, tips and tricks and useful insights to optimize your sample prep.
The pressure is always there to deliver accurate, reliable data, consistently and, if possible, at lower cost. Sample preparation is critical for success.
