Gas Chromatographic Analysis of Some Toxic Organic Compounds in Mainstream Cigarette Smoke Udc:543.544.3
In order to protect the human health from harmful effects of smoking, we consider the magnitude and range in levels of various groups of toxic organic compounds: polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), phenols and chloroorganic pesticides in mainstream cigarette smoke, obtained from Yugoslav blend cigarette. The cigarette smoke condensate was collected with el...
متن کاملHigh-resolution gas chromatographic profiles of volatile organic compounds produced by microorganisms at refrigerated temperatures.
Three different strains of bacteria isolated from spoiled, uncooked chicken were grown in pure culture on Trypticase soy agar supplemented with yeast extract. The volatile organic compounds produced by each culture were concentrated on a porous polymer precolumn and analyzed by high-resolution gas chromatographic mass spectrometry. Twenty different compounds were identified. Both qualitative an...
متن کاملGas-chromatographic method of analysis for urinary organic acids. I. Retention indices of 155 metabolically important compounds.
Gas-chromatographic retention indices are given, in terms of methylene units, for 155 metabolically important compounds (mostly organic acids) as trimethylsilyl derivatives on 10% OV-1 and 10% OV-17 columns. Comprehensive references on metabolic diseases that can be diagnosed by detection of these metabolites are cross-indexed to facilitate the use of the methylene-unit list. With the data pres...
متن کاملA gas chromatographic procedure for detection of pathological organic aciduria.
A number of nonamino organic acids associated with inborn errors of metabolism can be detected by gas chromatography. The organic acids are extracted into ethyl acetate and diethyl ether, the extracts combined, and the solvents evaporated under nitrogen. The residue is taken up in carbon disulfide and an aliquot chromatographed on 5% neopentyl glycol adipate to separate short-chain fatty acids ...
