Section H - Sensors, automation and computing

Sensors are devices that respond to the presence of one or more analytes enabling qualitative and/or quantitative information to be obtained quickly and continuously. 

Electrochemical sensors are based on potentiometric, amperometric or conductimetric cells that generate signals from electrochemical reactions of the analyte or in response to the presence of particular chemical species related to it. 

Optical sensors respond to the absorption or fluorescent emission of electromagnetic radiation by analytes, indicators or analyte-receptor complexes at characteristic wavelengths, principally in the visible region, but also in the ultraviolet and near infrared spectral regions. 

Thermal sensors measure heats of reaction generated by the oxidation of 

I These are groups of sensors that allow simultaneous monitoring with different instrumental parameters so as to improve the selectivity of the system for a particular analyte or to monitor several analytes.
