ANALYTICAL METHOD AND APPARATUS FOR DETERMINATION OF TOTAL NITROGEN AND/OR CARBON CONTENTS IN AQUEOUS SYSTEMS Abstract of the Disclosure: An analytical method for determining rapidly and accurately the total nitrogen and/or carbon contents in aqueous systems containing nitrogenous and/or carbonaceous materials, which comprises introducing an aqueous solution containing nitrogenous and/or carbonaceous materials as a specimen to be analyzed together with a carrier gas into a reactor tube packed with a destructive oxidation catalyst and/or a reducing agent and/or an oxidizing agent and kept at certain elevated temperatures so as to decompose the nitrogenous and/or carbonaceous materials to nitrogen and/or carbon dioxide and measuring the amounts of nitrogen and/or carbon dioxide in the resulting gaseous mixture by the use of a thermal conductivity gas chromatograph, and an apparatus to be used for carrying out such method. - 1 -
