Separation of mono-, di-, and trihydroxy stereoisomers of bile acids by capillary gas-liquid chromatography.
Capillary gas-liquid chromatographic separation was studied for the complete set of the 26 theoretically possible isomers of mono-, di-, and trihydroxylated 5 beta-cholanic acids, which differ from one another in the number, position, and configuration of hydroxyl groups at C-3, C-7, and/or C-12 in the nucleus, as well as for some of their related acids. The bile acid samples were chromatograph...
متن کاملSeparation of mono- and diglycerides by gas--liquid chromatography.
The parameters affecting the separation and quantification of trimethylsilyl ethers of mono- and diglycerides have been investigated by gas-liquid chromatography with QF-1 and SE-30 as stationary phases and a flame ionization detector. Results have been compared with those obtained earlier for triglycerides. The isothermal characteristics of a range of trimethylsilyl ethers of mono- and diglyce...
متن کاملPerchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry
Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
متن کاملIdentification and determination of different alkaloids from Atropa belladonna L. by Gas chromatography method
Background & Aim: A. belladonna (family: Solanaceae) is one of important pharmaceutical plants which contain tropane alkaloids. Tropane alkaloids are distinct group of secondary metabolites of the Solanaceae family. The most important alkaloids of A. belladonna are atropine and hyoscine that are used extensively because of their medicinal properties. There...
متن کاملDisopyramide determination by gas chromatography, liquid chromatography, and gas chromatography--mass spectrometry.
Disopyramide is determined in serum by gas chromatography with a nitrogen-selective detector, by liquid chromatography, and by gas chromatography--mass spectrometry. Comparable results are obtained with the three techniques, with a within-run and between-run precision of 5 to 10% (coefficient of variation). Least-squares analysis of data on patients' sera, analyzed first by gas chromatography (...
