RT Journal Article SR Electronic T1 A rapid micro-method for the screening and measurement of barbiturates and related compounds in plasma by gas-liquid chromatography JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 899 OP 904 DO 10.1136/jcp.25.10.899 VO 25 IS 10 A1 R. J. Flanagan A1 G. Withers YR 1972 UL http://jcp.bmj.com/content/25/10/899.abstract AB A rapid gas-chromatographic method has been developed for the determination of butobarbitone, amylobarbitone, hexabarbitone, pentobarbitone, quinalbarbitone, phenobarbitone glutethimide, and methaqualone in `finger-prick' samples of plasma. This has been applied to the analysis of some of these drugs in plasma taken from patients after therapeutic dosage and over-dosage.
