✦ Synopsis

The halide salts (chloride, bromide, iodide) of strontium and barium have been investigated

as column packings in gas-solid chromatography. Various groups of organic compounds have been studied, their heats of adsorption calculated and models presented to explain their behavior on these columns. Sample size required to produce overloading generally increased with increasing anion size in the packing. Retention volumes generally followed boiling points; two compounds having the same boiling point a greater adjusted retention volume was noted for the more polar compound. Chain branching reduced retention volume. Adjusted retention volume increased as size of anion in packing increased.

The method involves a single extraction of the drug and the internal standard, etidocaine, from alkalinized plasma with n-hexane. The gas chromatograph is equipped with a glass column (2.0 m x 2 mm) packed with 3% W/W SP2250 on Chromosorb W, (80/100 mesh) and a nitrogen sensitive detector. The metho
