A Procedure for the Sensory Analysis of Gas Chromatographic Effluents
A method ispresentedfor determining those volatile components of Jbods that have flavour significance. The method leads to quantitative flavour specifications called charm that can be displayed graphically. The procedure is baaed upon the relative odour detection thresholds of volatile compounds of known gas chromatographic retention indices.
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 ...
متن کاملRapid gas chromatographic assay for pregnanolone in pregnancy urine.
GAS CHROMATOGRAMS of chloroform extracts of hydrolyzed pregnancy urine have a characteristic appearance (1). Three major peaks appear regularly and are thought to be associated with a group of li-desoxy17-oxosteroids, with pregnanolone, and with preglianediol, respectively. During a study of the effect of acid concentration 011 the rate of hydrolysis of urinary pregnanediol glucuronide, it was ...
متن کاملRapid gas-liquid chromatographic method for plasma verapamil level determination.
Verapamil is a newly marketed antiarrhythmic drug. It has a significant presystemic elimination when administered orally and, therefore, intravenous therapy is often recommended. Optimum therapeutic effect is obtained when verapamil plasma concentrations are between 100 and 400 ng/ml. Several chromatographic procedures for the determination of verapamil in biological fluids have been described ...
متن کاملRapid gas-chromatographic measurement of anticonvulsant drugs in serum.
We describe a rapid method for precisely measuring concentrations of anticonvulsant drugs in serum. The simple procedure, adaptable to the clinical laboratory, can be used for the routine simultaneous measurement in sera of phenobarbital, primidone, dephenylhydantoin, and (or) ethosuximide. The extraction procedure requires no solvent evaporation and gives a good yield for primidone and quantit...
