Analytische O-FID-Vorrichtung und Verfahren

摘要

An anlytical equipment and method for the selective detection of individual oxygenated compounds in complex organic mixtures, in particular fuels, comprising, downstream an equipment of chromatographic separation, a cracking reactor, a catalytic hydrogenation microreactor and a FID detector. The cracking reactor is provided with a catalyst under the form of metal elements, made of palladium, inserted inside the capillary tube though which flows the gas under test. Thanks to the present equipment, the analytical process, based on the specific response of oxygenates to the method of flame ionization detection (O-FID), foresees that the cracking reaction takes place at temperatures below 1000 degrees C and, consequently allows to keep the cracking reactor at stand-by temperatures below 700 degrees C.
