Abstract
PURPOSE:To perform the analysis of inorg. carbon and org. carbon due to a halogen compound in a water specimen, by filling a reaction tube for converting inorg. carbon to CO2 with a non-oxidative acid containing Ag<+> to remove halogen. CONSTITUTION:In the analysis of inorg carbon (IC) such as carbonic acid or carbonic ion in rivers, ocean, sewage or industrial waste water, a reaction tube 2 converting IC to CO2 succeeding to a carrier supply part 1 is filled with one obtained by impregnating a holding material 8 such as a quartz glass chip with a non-oxidative acid such as H3PO4 containing Ag<+> or directly filled with an acidic silver phosphate crystal. A specimen is sent from an injection part 2' while a carrier gas is sent to immobilize the halogen in the specimen as silver halide by the packing material 8 and the product gas is passed through a dehumidifier 3 along with the carrier gas to be sent to a gas analytical part 4. The measured value of CO2 is recorded by a recorder 7. When org. carbon is measured, the reaction tube 8 is aranged next to a combution tube holding an oxidizing catalyst. By this method, the influence of halogen is eliminated to perform accurate analysis of C due to an infrared analyser.
