Gas detection apparatus having two measurement chambers and two detectors

A gas detection apparatus for the detection of at least one target gas in at least one gas mixture, wherein the gas detection apparatus comprises:

• a radiation source configured to emit electromagnetic radiation, a first measurement chamber, a second measurement chamber, a first measurement detector, and a second measurement detector,
• wherein the second measurement chamber is spatially separated from the first measurement chamber,
• wherein the gas detection apparatus is configured in such a way that a first gas mixture flows through the first measurement chamber and a second gas mixture flows through the second measurement chamber,
• wherein the gas detection apparatus is configured in such a way that electromagnetic radiation emitted by the radiation source passes initially through the first measurement chamber and subsequently through the second measurement chamber,
• wherein the first measurement detector is configured to:
• measure a gauge of a physical effect in the first measurement chamber caused by electromagnetic radiation which passes through the first measurement chamber and correlating with a presence of the at least one target gas in the first measurement chamber, and
• generate a first signal correlating with the physical effect in the first measurement chamber,
• wherein the second measurement detector is configured to:
• measure a gauge of a physical effect in the second measurement chamber caused by electromagnetic radiation which passes through the second measurement chamber and correlating with the presence of the at least one target gas in the second measurement chamber, and
• generate a second signal correlating with the physical effect in the second measurement chamber, and
• wherein the first measurement detector is configured to detect at least one predetermined target gas in the first measurement chamber and to generate a signal correlating with the presence or absence of the at least one target gas as the first signal, and the second measurement detector is configured to analyze the gas mixture in the second measurement chamber and to generate a signal correlating with a composition of the gas mixture as the second signal.
