ABSTRACT:
A method and apparatus for sample screening and sample preparation within a vessel sealed with a cap, the vessel having at least a portion of the inside surface coated with a stationary phase having an affinity for analytes of interest. A sample possibly containing such analytes is introduced into the vessel whereby the analytes of interest migrate out of the sample and into the stationary phase for detection by a screening device and for desorption.
