GAS SENSOR WITH A MICROPOROUS ELECTROLYTE LAYER

摘要

The electrochemical sensor comprises a working electrode (3), a counter electrode (5) and an electrolyte layer (6). The electrolyte layer comprises a particulate material and a binder, which together form a porous and non-swellable framework structure. The pores in the framework structure are provided for receiving a liquid electrolyte. The particulate material is a zeolite, particularly a faujasite. The liquid electrolyte includes alkali metal chloride and a pH-buffer system. The liquid electrolyte includes an enzyme, particularly carbonic anhydrase. Independent claims are included for the following: (1) a method for manufacturing electrochemical sensors; and (2) a method for determining gaseous analytes dissolved in an aqueous measuring medium using electrochemical sensors.
