SPECTROPHOTOMETRIC AND GAS CHROMATOGRAPHIC METHODS FOR DETECTION AND ASSAY OF MUSTARD GAS
A colorimetric method for detection and assay of mustard gas in urine after addition of thymolphthalein is reported. The detection limit was 80 ng/ml of llrine. Mustard gas could also be detected in urine after extraction with gas chromatography using FID detector. The detection limit was 10 ng/ml. In addition, thiodiglycol, a metabolite of mustard gas, could be converted to mustard with ...
متن کاملGas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...
متن کاملDiscrimination of Different Hop Varieties Using Headspace Gas Chromatographic Data
Os métodos utilizados para caracterização do lúpulo envolvem a análise de substâncias amargas e do óleo essencial, seguida da comparação da composição química e perfis cromatográficos. No presente trabalho, diferentes variedades e produtos de lúpulo foram discriminados através da análise da composição dos óleos essenciais por cromatografia a gás no modo headspace em fase gasosa, com subsequente...
متن کاملAssays for chloramphenicol compared: radioenzymatic, gas chromatographic with electron capture, and gas chromatographic-mass spectrometric.
We compared these three techniques for measuring chloramphenicol in serum or urine. Although each has its particular advantages, any of them is shown to be satisfactory and may appropriately be used by clinical laboratories, according to the facilities available.
متن کاملGas-chromatographic assay for heme oxygenase activity.
We have developed an improved assay for microsomal heme oxygenase activity, based on the enzymic release of CO from the alpha-methene bridge of hemin and the quantitation of CO by gas chromatography. The within-run coefficient of variation (CV) of heme oxygenase assays in microsomes from rat tissues (liver, kidney) averaged 8%; the between-run CV averaged 15%. The detection limit for heme oxyge...
