Electrochemical sensors operate by reacting with the analyte and producing an electrical signal. Most electrochemical gas sensors are amperometric sensors, generating a current that is linearly proportional to the gas concentration. The principle behind amperometric sensors is the measurement of the current-potential relationship in an electrochemical cell where equilibrium is not established ...

An electrochemical sensor is a device that quantitatively detects a particular chemical species as an oxidation or reduction current [3, 25, 26]. An electrochemical sensor has advantages such as simple measurement procedure, short response time, and sufficient sensitivity and selectivity.
· ELECTROCHEMICAL SENSORS. Electrochemical sensors are made up of three essential components: a receptor that binds the sample, the sample or analyte, and a transducer to convert the reaction into a measurable electrical signal. In the case of electrochemical sensors, the electrode acts as the transducer. 6 Figure 1: Schematic illustrating the basic components of an electrochemical sensor.
electrochemical sensors is that they are all the same. In fact, the appearance of the electrochemical sen-sors used to detect various gases may be similar, but their functions are markedly different. Consequently, Fig. 1. Electrochemical Sensors. 28 Hazardous Gas Monitors one can expect varying performance from each of these sensors, in terms of sensitivity, selectivity, re-sponse time, and ...
Electrochemical sensors operate by reacting with the gas of interest and producing an elec-trical signal proportional to the gas concen-tration. A typical electrochemical sensor con-sists of a sensing electrode (or working elec-trode), and a counter electrode separated by a thin layer of electrolyte, Figure 3. Gas that comes in contact with the sensor
Electrochemical sensors are stable, reliable, fast, require very little power and are capable of providing resolution up to ppm (depending on the sensor and contaminant). They respond only to some particular gases. Most of these sensors have been carefully designed to minimize the effects of common interfering gases. Though care has been taken to reduce cross sensitivity, some interfering ...
Electrochemical sensors are among the mostly explored microsensors for their versatility, portability, and fast response. Such sensors, being electrochemical in nature, are normally based on a redox reaction involving the target analyte in the electrolyte at a working electrode, resulting in the variation of an electrical signal.
