Abstract
A gas detection system, comprising a sample gas inlet, a reference gas inlet and a gas modulation valve alternatingly connecting one of the sample gas inlet and the reference gas inlet to a gas sensor, is characterized in that a selective transfer filter is located in the gas flow path connecting the gas modulation valve and the gas sensor.
