Device for identifying at least one gaseous component in a gaseous or liquid sample, and identification method

摘要

A device is disclosed for the identification of gaseous components in gaseous or liquid samples. This device exhibits a sensor having sensitivity for the component to be identified, for example a corresponding optical sensor, and furthermore a gas-permeable membrane preventing direct contact of the sensor with the liquid or gaseous sample, but permitting the component thereof, to be identified, to pass through. As compared with heretofore known, corresponding devices, the novel device differs in that the gas-permeable membrane is located directly on the sensor and is mechanically supported by the latter. The novel device exhibits a high sensitivity and a short response time.
