Analyzing device including an ion-permeable channel connecting a sample chamber with a reaction space |
摘要 |
In a device for determining the concentration of a reagent from a group consisting of gases with acid or alkaline reaction in aqueous environments, and volatile acids and bases in liquid or gaseous samples, a sample chamber is situated in a housing and a unit for pH measurement with a reaction space is separated from the sample chamber by an ion-impermeable, gas-permeable membrane. The feeding of the reaction space with buffer solution is facilitated by connecting the reaction space by means of an ion-permeable channel to a reservoir for a buffer solution located outside of the pH measuring unit.
