Replicates of whole colonies of four species of closely related dermatophytes were analyzed by pyrolysis gas-liquid chromatography (PGLC). The four species included fifteen strains of Arthroderma tuberculatum, and two strains each of A. benhamiae, Nannizzia gypsea and N. incurvata. Individual peaks
Asphaltenes derived from tar from the flash pyrolysis of Millmerran coal have been separated into acid, base, polyfunctional and neutral fractions by ion-exchange chromatography. Each fraction was studied by high-pressure catalytic hydrogenolysis followed by g.c.-m.s. analysis of the volatile produ
The asphaltene fraction from a super-critical gas (SCG) extract of bituminous coal was pyrolysed under nitrogen at temperatures from 200 to 45o"C, and the resultant pyrolysate re-fractionated into four conventional solubility classes (n-pentane-soluble, benzene-soluble, pyridine-soluble and pyridine
