ABSTRACT:
Colorimetric measuring arrangement comprising a reaction chamber in which the gas to be measured is absorbed in a reaction liquid and enters into a color reaction. The reaction chamber is in the form of an atomizer in which the reaction liquid is atomized into very fine droplets and thus provides a large surface for the adsorption of gas. The reaction chamber is adjoined by a separation pipe in which the gas phase is re-separated from the reaction liquid. The separation pipe communicates through a liquid guide with an inlet funnel which opens into a micro-throughflow cell. The outlet of the micro-throughflow cell is connected to a siphon. These measures avoid troublesome pulsations in the micro-throughflow cell.
