Abstract:
The present invention is directed to a disposable specimen collection device comprising a specimen chamber (1), a closing element (10) and a cutting element. The specimen is preferably hair or feathers and the device is preferably used for extracting analytes from the specimen.
Abstract:
An extraction apparatus includes extraction fluid sources (9), modifying agent source (3), extraction cartridges (2) with extraction chambers (1), and collection vessels (13) connected by tubing and multiport valves (16, 17, 18, 19, 20, 21) for ease of automation.
Abstract:
A method for extracting and detecting metabolically associated analytes from biological samples using supercritical fluid extraction (SFE) and chromatography (SFC) is disclosed. Also disclosed is a method for distinguishing between those analytes that are environmentally associated from those that are metabolically incorporated.
