System and method for determining a concentration of an analyte in a carrier gas of a quasi-binary or binary gas mixture

A system for determining a concentration of an analyte in a carrier gas of a gas mixture, comprising:

• an electrochemical gas sensor,
• wherein the electrochemical gas sensor comprises a working electrode and a counter electrode,
• wherein the electrochemical gas sensor is configured by means of the working electrode to:
• perform at least one of:
• oxidizing the analyte, or
• reducing the analyte;
• perform at least one of:
• reducing at least one component of the carrier gas, or
• oxidizing the at least one component of the carrier gas;
• and
• provide a measurement signal;
• a memory unit storing calibration information for the gas mixture;
• and
• a data processing unit configured to:
• receive the measurement signal;
• receive the calibration information;
• determine the concentration of the analyte in the carrier gas based on the measurement signal and based on the calibration information;
• and
• provide the determined concentration of the analyte in the carrier gas.

A method for determining a concentration of an analyte in a carrier gas of a gas mixture, comprising:

• receiving, by a data processing unit, a measurement signal,
• wherein the measurement signal corresponds to one or more of:
• oxidation of the analyte, or
• reduction of the analyte, and
• wherein the measurement signal further corresponds to one or more of:
• reduction of at least one component of the carrier gas, or
• oxidation of the at least one component of the carrier gas,
• at a common working electrode;
• receiving calibration information for the gas mixture;
• determining the concentration of the analyte in the carrier gas based on the measurement signal and based on the calibration information;
• and
• providing the determined concentration of the analyte in the carrier gas.
