Particle and VOC sensing technology from ION Science, delivers OEMs a wider solution for air quality management

ION Science is committed to protecting lives and preserving the environment by offering pioneering gas sensing technology that monitors and improves air quality. Two key air quality pollutants that ION can detect are Volatile Organic Compounds (VOCs) and Particulate Matter (PM). 

Particulate matter pollution is an enormous problem across the world. An estimated 91% of the world’s population lives in areas where air quality levels exceed WHO limits. Particulate matter sensors measure the quantity and size of (fine) dust particles, with both parameters influencing air quality. The NextPM particulate matter sensor now available from ION, has been independently verified by the South Coast AQMD as the world’s best-performing, low-cost particulate sensor. It features advanced technical innovations that enable ultra-precise measurements to be obtained, even in extreme climatic conditions. Including direct measurement of PM1, PM2.5 in both μg/m3 and pcs/L, compared with most alternatives that only measure one fraction, and smart sample conditioning to remove humidity effects. 

Volatile organic compounds have a high vapor pressure and low water solubility. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. VOCs include a variety of chemicals, some of which have short- and long-term adverse health effects. Concentrations of many VOCs are typically higher indoors (up to ten times higher) than outdoors and the easiest way to manage VOCs inside of buildings is a ventilation system. 

Monitoring VOCs, both indoor and outdoor is important, to ensure that harmful levels are not reached, the ION PID sensor variants most suitable for air quality monitoring are: 

MiniPID 2 PPB Sensor is optimised to low-end ppb sensitivity while offering a wide dynamic range and is perfect for measuring indoor and outdoor air quality over a wide range of environments. 

MiniPID 2 HS Sensor is the most sensitive VOC sensor on the market designed for high sensitivity applications, allowing sub ppb measurement. 

MiniPID 2 10.0 eV Sensor is a good choice for spaces that require selective measurement of highly toxic VOCs such as benzene, toluene, ethylbenzene, and xylene. 

ION Science’s PID technology is ideal for air quality and emissions monitoring purposes, thanks to the patented fence electrode technology found in all ION Science MiniPID sensors, this helps to eliminate false positives, delivering reliable results. 

Using the two gas sensing technologies, MiniPID sensors and NextPM particle sensors, in combination, is an effective way to monitor air quality and emissions for the safeguarding of human and environmental health.
