✦ Synopsis
A screening procedure is described for the identification of barbiturates, amphetamines and narcotics in urine . A simple pH adjustment and extraction with organic solvents is followed by a combination of thin-layer and gas-liquid chromatography. Interference and interpretation are discussed, with special reference to the metabolites of barbiturates, nicotine and phenothiazines .
