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.
Claims15
A device, through which a gas sample can flow, for detecting chlorine dioxide, the device comprising:
- a reagent flow space with reagent therein to expose the gas sample to be analyzed to said reagent for removing chlorine, said reagent containing cyclohexylsulfamic acid and/or salts thereof;
- and
- an indicator or an electrochemical cell forming a chlorine dioxide qualitative and/or quantitative determination means for a qualitative and/or quantitative determination of chlorine dioxide.
A method for detecting chlorine dioxide in a gas sample, the method comprising;
- exposing the gas sample to be analyzed to a reagent for removing chlorine;
- and
- subsequent to said step of exposing the gas sample to the reagent, passing the gas sample to a chlorine dioxide determination means comprising an indicator or an electrochemical cell for the qualitative or quantitative determination of chlorine dioxide, wherein the reagent for removing chlorine is or contains cyclohexylsulfamic acid and/or salts thereof.
