Micro Gas Chromatography for Liquid Petroleum Gas's

For years, microGC analysis has been useful as a powerful tool for the fast and reliable analyses of natural gas and other gaseous matrices; but, it is yet to prove its capabilities for liquid samples. In this paper, we present a unique gasifying system for volatile liquid sample introduction in a microGC. The system has been tested with a wide range of different samples: liquefied gases (ethan...

Wine: Gas and Liquid Chromatography

From the chemical point of view, wines are aqueous alcoholic solutions containing more than 1000 components that can be present at high concentrations (g L ), but also at trace levels (ng L ). Some of these components determine the organoleptic properties of wines, while others are signi"cant for classifying their origin and/or for checking whether some adulteration has taken place. Concentrati...

Determination of Organic Sulfur Contaminants Using Hollow Fibre-protected Liquid-phase Micro-extraction Coupled with Gas Chromatography

A simple and solvent-minimized sample preparation technique based on hollow fibre-protected liquid-phase micro-extraction has been developed for extraction of fifteen organic sulphur compounds from aqueous samples. The analysis of the extracted them was performed by gas chromatography equipped with mass spectrometry and/or flame photometric detectors. 3.3 µL of organic solvent located in the lu...
