DISPOSITIVO PER L' ANALISI DI COMPOSTI ORGANICI , PARTICOLARMENTE IN C AMPIONI ACQUOSI E GASSOSI .

摘要

A device for analyzing organic compounds, particularly in aqueous and gaseous samples, constituted by a duct (4) which is supplied in input by a gas whose pressure can be controlled by means of a regulator (5) connected to a capillary column (6) which is connected in output to a detector (14) for the organic compounds; an adsorbent polymer (7) immersed in a container (8) is interposed between a first portion (6a) and a second portion (6b) of the capillary column (6), and the device comprises, between the second portion (6b) and a third portion (6c), means (6d) for concentrating the organic compounds; the container (8) contains an aqueous or gaseous sample which interacts with the adsorbent polymer (7) adapted to extract the organic compounds conveyed by the gas in passing through the adsorbent polymer (7) toward the concentration means (6d) in order to be measured by the detector (14).
