Measurement of urinary hippuric and m-methylhippuric acids by gas chromatography.
Buchet, J. P., and Lauwerys, R. R. (1973). British Journal ofIndustrial Medicine, 30, 125-128. Measurement of urinary hippuric and m-methylhippuric acids by gas chromatography. A gas chromatographic method for the determination of hippuric and m-methylhippuric acids in urine is described. A known amount of heptadecanoic acid (internal standard) is added to the urine before its extraction with e...
متن کاملQuantitative determination of hippuric and m-methylhippuric acids in urine by high-speed liquid chromatography.
High-speed liquid chromatography employing an ultraviolet photometric detector has been applied to the simultaneous determination of hippuric and m-methylhippuric acids in urine. Reversed-phase partition chromatography is carried out on a muBondapak C18 column with methanol-water as the eluent system. This method obviates the necessity for isolation or reaction of these acids before assay. The ...

متن کاملThin-layer chromatography of hippuric and m-methylhippuric acid in urine after mixed exposure to toluene and xylene.
The separation of hippuric and m-methylhippuric acid as toluene and m-xylene metabolites present in urine of people exposed simultaneously to toluene and xylene is described. Chloroform was used for hippuric and m-methylhippuric acid extraction. Satisfactory separation of these metabolites was obtained on TLC plates covered with silica gels and developed in chloroform acetic acid-water (4:1:1);...
متن کاملEvaluation of Toluene Exposure in Workers at Industrial Area of Sidoarjo, Indonesia by Measurement of Urinary Hippuric Acid
Background: Toluene is a harmful substance still being used as a solvent and catalyst in many industries that can increase the level of urinary hippuric acid (UHA). This study was designed to examine the level of toluene and UHA among workers of industrial site in seven companies in Sidoarjo, Indonesia and to analyze the risk factors for abnormal UHA. Methods: This study was an analytical cross...
