  • Device for determining chlorine dioxide and method
    Patent number: 7744815
    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.
    Type: Grant
    Filed: September 25, 2007
    Date of Patent: June 29, 2010
    Assignee: Dräger Safety AG & Co., KGaA
    Inventors: Holger Bohm, Andreas Mohrmann, Bettina Runge, Armin Schulten

  • Device and method for detecting sulfuryl fluoride
    Patent number: 7201877
    Abstract: A device for detecting sulfuryl fluoride, in which the gas specimen to be examined is subjected to pyrolysis with ensuing detection of a pyrolysis product, is to be improved for the sake of achieving a mobile, economical structure. To attain this object, in a preliminary tube (1) for pyrolysis, there is a chemical layer (5) of pyrophoric iron, and as an indicator system for the pyrolysis product, a test tube (2) for hydrogen fluoride is used.
