Headspace Gas Chromatography
possibility of very selective separations that depend on the geometry of the molecules to be separated rather than the more generalized solubility mechanisms acting in gas}liquid chromatography. It should be theoretically possible to design adsorbents for particular separations. In the branch of liquid chromatography known as afRnity chromatography, for example, it is already possible to manufa...
متن کاملQuantitative endogenous formate analysis in plasma using headspace gas chromatography without a headspace analyzer.
The objective was to develop a simple routine method for quantitative measurement of endogenous formic acid in plasma and whole blood using headspace gas chromatography-flame ionization detection. (GC-FID). Two-hundred microliters of sample was placed in a 1-mL glass vial. Fifty microliters of aqueous ethanol (10%) was added as an internal standard and a derivatizing agent. Ethylformate formati...
متن کاملDetermination of Volatile Substances in Forensic Samples by Static Headspace Gas Chromatography
The technique of static headspace gas chromatography has great acceptance in the forensic field, especially for the determination of ethanol in biological samples (Macchia et al., 1995; Tagliaro et al., 1992), so most forensic laboratories in the world have this equipment and perform this analysis on a routine basis, but in many of these laboratories, equipment is exclusively employed to determ...
متن کاملSimultaneous Determination of Disinfection By-products in Water Samples from Advanced Membrane Treatments by Headspace Solid Phase Microextraction and Gas Chromatography-Mass Spectrometry
A headspace-solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) method has been developed for the simultaneously determination of 20 disinfection by-products (DBPs) in water samples from reverse osmosis (RO) membranes. Selected compounds belong to different families including: trihalomethanes (THMs), halogenated acetonitriles (HANs), halogenated nitromethanes ...
متن کاملelimination of btex , voc vapors from glycol in gas hydrant unit
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
