When diatomaceous earth and glass columns are acylated prior to coating with a silicone liquid phase, then subjected to heat treatment in an atmosphere of nitrogen, gas chromatographic columns can be prepared that show a marked reduction in adsorptio

The behaviour is described of several barbiturates when subjected to chromatography on filter paper impregnated with olive oil. Results are given for various methanolic and aqueous inorganic solvents. The technique affords a fairly rapid separation o

The surface properties of diatomaceous earth and of oxidised stainless steel can be modified to produce GLC columns which show very little adsorption and which can by used for GLC analysis of submicrogram amounts of alkaloids . The modification is ef

A method for the detection of barbiturates in blood is described. The method, which uses chromatography on ion-exchange paper, can be extended for identification of the type of barbiturate. A semi-quantitative result can be obtained without an ultrav

The behaviour of barbiturates when subjected to reversed phase paper chromatography with an aqueous solvent at elevated temperatures is described. With the exception of Pentobarbitone and Amylobarbitone, differentiation of thirteen different barbitur

This paper describes the gas-liquid chromatographic separation of mixtures of barbiturates in pure solution and in extracts of biological material. Using a special preparation of SE-30-tristearin on acid-washed Chromosorb W in a stainless steel colum

The ultraviolet spectra and some other properties of products obtained by the action, on some commonly used barbituric acid derivatives, of different strengths of sulphuric acid at 100° have been studied. In this work the products examined included

Many forensic problems using GLC are similar to those of workers in other fields whose material is of biological origin. This paper is concerned with some of the problems encountered in the analysis of alkaloids by GLC. Because alkaloids are polar co
