Abstract

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