ABSTRACT:
A high purity styrene-divinyl benzene resin is used for rapid solid phase extraction of drugs of abuse from body fluid samples. Simple extraction procedures are described which provide high recovery and selectivity for a wide variety of drugs. A convenient method of increasing flow rate in such solid phase extractions is also described.
