An electrochemical sensor known as an amperometric gas sensor is used to find the presence of gases in a given environment. It operates by monitoring the current flow between two electrodes while a gas is present.
A working electrode and a reference electrode make up the sensor's two electrodes. Usually formed of a noble metal or metal oxide, the working electrode has a catalyst coating that reacts with the gas being detected.
A steady reference potential is provided by the reference electrode, which is typically comprised of a stable metal like platinum.
An electrochemical reaction occurs when a gas molecule interacts with the catalyst on the working electrode. This reaction results in the transfer of electrons from the gas to the electrode.
The current flow between the working and reference electrodes is produced by this electron transfer and is proportional to the gas concentration in the surrounding environment.
Toxic gases like carbon monoxide, hydrogen sulphide, and chlorine are frequently found in industrial applications where amperometric gas sensors are utilised to detect them. They are also utilised for assessing the quality of the air within buildings and environmental monitoring.
Global amperometric gas sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Their amperometric 4-electrode air quality sensors are the ideal match for the Alphasense VOC electrochemical VOC-A4 and VOC-B4 sensors. The VOC-A4 and VOC-B4 should be used in conjunction with one of our CO-A4 or CO-B4 carbon monoxide sensors in ambient air quality applications.
Although we advise utilising these sensors at 0V for air quality applications, the VOC-A4 and VOC-operating B4's voltages can be changed to run at V, 0.1V, 0.2V, or 0.3V, giving the user the flexibility to detect a variety of gases.
The VOC-A4 and B4 are designed to function in conjunction with their current line of sensors and can identify a wide range of chemicals, including benzene, formaldehyde, and ethanol.
Both sensors can be utilised in custom circuits, with their individual sensor boards (ISB) in the case of the B4 or with other sensors in their multiport Analogue Front-End boards (AFE) in the case of the A4, and both have great response times and low power consumption.
