Alcohol analysis using gas chromatography.Peer-reviewed article

L. PROCHÁZKA, J. ČULÍK

The determination of organic contaminants in alcohol was tested using gas chromatography. S possible application of the GLC method (the packing material was Carbowax 20M) and the GSC method (with Porapack and Separon) was performed on the gas chromatograph CHROM 5. The best separation efficiency, sensitivity and low detection limit of compounds tested was achieved with Separon CHN. The optimum conditions for the analysis were found. The level of the individual contaminants can be quantitatively determined up 1 mg . l^-1. Alcohol from the fermentation usually contains about 7-10 mg of methanol per litre. The quantitative determination of acetaldehyde remains unresolved.
