Abstract
Method for wide range gas detection using a gas detection system comprising a sample gas inlet, a reference gas inlet, a gas modulation valve and a gas analyzer, wherein the gas modulation valve alternatingly connects the sample gas inlet to the gas analyzer during a sample gas time period and the reference gas inlet to the gas analyzer during a reference gas time period, characterized in that the sample gas time period is shorter than the reference gas time period such that the sample gas concentration in the gas analyzer is reduced.
