Abstract

A method is proposed for the contiuous determination of gaseous oxidation products from industrial process, drinking and/or waste water, particularly for determining the TOC value, at least the organically bound carbon contained in a test solution to be investigated being oxidatively transformed and the gaseous oxidation products are supplied to a measuring unit, where at least the organically bound carbon is detected, the test solution being continuously pumped into a microreactor, where it is heated to a predetermined temperature and the organic compounds in the test solution are continuously oxidatively transformed under a temperature and pressure increased in a defined manner. An apparatus for the continuous determination of gaseous oxidation products from industrial process, drinking and waste water, particularly for determining the TOC value, having an oxidation unit and a following measuring unit has a terminally open heatable microreactor as the oxidation unit, upstream of which is provided a high pressure pump for the continuous supply of the test solution.
