· VOC Sensors Currently, there are a wide range of gas sensors and sensor arrays used for the detection of VOCs. For example, colorectal sensors, quartz microbalance sensors, surface acoustic wave sensors and chemiresistors or chemicapacitors. However, these methods used for VOC detection are limited by humidity which can interfere with their performance. Furthermore, these sensors …
· Cost. Electrochemical VOC sensors. With resolution from 10 to 50ppb, electrochemical cells are lowcost, lowpower, compact sensors. Electrochemical sensors need to be optimised for the target VOC because each VOC requires a different ideal bias voltage for best sensitivity. Also, electrochemical cells respond in about 25 seconds, in comparison with onetotwo seconds for PIDs. Nevertheless, electrochemical sensors are suitable for some applications, where cost …
Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors …
