SENSOR FOR ANALYSING OXIDISING GAS, METHOD FOR PRODUCING SAID GAS AND METHOD FOR DETERMINING THE CONCENTRATION OF THE OXIDISING GAS

摘要

The inventive electrochemical sensor for determining the concentration of an oxidising gas in the studied gas or liquid comprises a body containing an electrolyte and measuring and counter electrodes contacting said electrolyte. The counter electrode contains carbon material and has a potential equal to or higher than 750 mV when it is measured in relation to a hydrogen reference electrode in the same electrolyte. The inventive method for producing said electrochemical sensor and determining the oxidising gas in the studied gas is also disclosed.
