CURRENTLY COMMERCIALLY AVAILABLE CHEMICAL SENSORS EMPLOYED FOR DETECTION OF VOLATILE ORGANIC COMPOUNDS IN OUTDOOR AND INDOOR AIR
Szulczynski, B. and J. Gebicki.
Environments 4(1):21(2017)

This review discusses the principles of operation and design of the most popular chemical sensors for measurement of VOCs in outdoor and indoor air, encompassing sensors for detection of toxic compounds, such as electrochemical (amperometric), photoionization, and semiconductor with solid electrolyte sensors, as well as sensors for evaluation of explosion risk, including pellistors and IR-absorption sensors. The metrological parameters—measurement range, limit of detection, measurement resolution, sensitivity, and response time—are presented for each, including development trends and prospects for metrological parameter improvement. http://www.mdpi.com:8080/2076-3298/4/1/21/pdf
