Systematic analysis of solvents and other volatile substances by gas chromatography.
Four column packings for screening volatiles in biological material by gas chromatography are evaluated. Retention data are standardized by the calculation of retention indices, and packing materials are compared by discriminating power and identification power. A combination of 5% Carbowax 20M on Carbopack B and 0.3% Carbowax 20M on Carbopack C appears to be best suited for screening. Hydroxy-n-alkanes are used as reference substances for the calculation of retention indices.
