Abstract
A gas-liquid chromatographic procedure has been developed to separate and quantitate various drug mixtures. The samples are extracted by various techniques and determined by the use of a polar (4 percent cyclohexanedimethanol succinate) or a polar-nonpolar (1 percent cyclohexanedimethanol succinate plus 10 percent SE 52 silicone gum rubber) gas-liquid column. Retention data relative to pentobarbital are presented for 50 drug materials. Quantitative data are presented for 25 different drugs found in 19 commercial preparations, and for 7 synthetically prepared drug combinations. Recoveries ranged from 96 to 106 percent.
