Diffusion chamber for determination of different parameters of aqueous substance, has sample carriage inserted in central cylinder, where sample carriage has cylindrical opening, above which sealing ring is arranged on sample carriage

摘要

The diffusion chamber (01) has a sample carriage (20) which is inserted in a central cylinder (03) in a gas-tight and radial manner, where the sample carriage has a cylindrical opening (21), above which a cylindrical sealing ring (22) is arranged on the sample carriage. An obliquely extended groove is formed, in which a cannula (11) of a pH-measuring sensor is inserted. The pH-measuring sensor is formed as syringe-type optical micro-sensor (07). An optical fiber (09) is displaceably mounted in the cannula.
