Application of electrochemical sensors and sensor matrixes for measurement of odorous chemical compounds

• It presents the principle of operation of electrochemical sensors for measurement of odorous compounds.
• Comparison of the advantages and disadvantages of electrochemical sensors for measurement of odorous compounds.
• It presents the principle of operation of the e-nose.
• Presented of commercial electronic noses built with electrochemical sensors.

In this paper describes the principle of operation of the electrochemical sensors and the sensor matrixes comprised of electrochemical sensors intended for measurement of odorous compounds. Critical comparison of these sensors' advantages and disadvantages has been made. The fields of economy contributing to release of odours and the potential sources of their emission have been identified. Commercially available electrochemical sensors and sensor matrixes for measurement of odorous compounds have also been presented.
