Title: DEVICE AND METHOD FOR DETECTING GAS
Abstract:
An analyser (1) for detection of a target compound (64) in a complex gas mixture (6) in the gas phase is provided. The analyser (1) comprises a detector (3) for detecting the target compound and further comprises a sensing cavity (41). The detector (3) is arranged in the sensing cavity (41). The analyser (1) further comprises a separate first membrane (2,21), wherein the first membrane (2,21) is equipped to close the cavity (41). Furthermore, the first membrane (2,21) is equipped for simplifying the composition of the complex gas mixture (6) into a first gas mixture (61), wherein the first gas mixture (61) comprises the first target compound (64) and wherein the first membrane (2,21) is equipped to let the first gas mixture (61) traverse through the first membrane (2,21) into the sensing cavity (41). The detector (3) is equipped to detect the first target compound (64).
