Analysis of gaseous constituent of samples, e.g. carbon dioxide for TOC determination in water, involves transferring the gas from a sample receiver via an adapter to an analysis vessel fitted with a pressure equalizer

摘要

Gaseous constituents of a sample are analyzed by transferring the constituent from a sample receiver via an adapter into an analysis vessel containing an indicator reagent and connected to the external atmosphere in such a way as to equalize the pressure. A method for the analysis of a gaseous or vaporizable constituent (23) of a sample (5), in which the sample (5) is filled into a sample receiver (2) through an inlet (4), an analysis vessel (7) containing an indicator reagent (8) is attached to inlet (4) via an adapter (10) and the constituent (23) is transferred from receiver (2) to vessel (7). In this system, vessel (7) is connected to the external atmosphere in such a way as to equalize the pressure. An independent claim is also included for a test kit for such analysis, comprising the above components, in which the analysis vessel (7) can be used as sample container in an optical measuring instrument and is also fitted with a pressure-release device (13).
