Abstract

A device and a method are provided for determining chlorine dioxide, especially in the presence of chlorine as a foreign gas. In the device the gas sample is exposed at first to a reagent for removing chlorine and subsequently to an indicator or to an electrochemical cell for the qualitative and/or quantitative determination of chlorine dioxide. The reagent for removing chlorine is or contains cyclohexylsulfamic acid and/or salts thereof. The device, through which flow can take place may be a test tube.
