Formaldehyde gas sensors: a review.

Chung PR, Tzeng CT, Ke MT, Lee CY - Sensors (Basel) (2013)

Bottom Line: Accordingly, the emergence of sophisticated technologies in recent years has prompted the development of many microscale gaseous formaldehyde detection systems.Besides their compact size, such devices have many other advantages over their macroscale counterparts, including a real-time response, a more straightforward operation, lower power consumption, and the potential for low-cost batch production.This paper commences by providing a high level overview of the formaldehyde gas sensing field and then describes some of the more significant real-time sensors presented in the literature over the past 10 years or so.

ABSTRACT
Many methods based on spectrophotometric, fluorometric, piezoresistive, amperometric or conductive measurements have been proposed for detecting the concentration of formaldehyde in air. However, conventional formaldehyde measurement systems are bulky and expensive and require the services of highly-trained operators. Accordingly, the emergence of sophisticated technologies in recent years has prompted the development of many microscale gaseous formaldehyde detection systems. Besides their compact size, such devices have many other advantages over their macroscale counterparts, including a real-time response, a more straightforward operation, lower power consumption, and the potential for low-cost batch production. This paper commences by providing a high level overview of the formaldehyde gas sensing field and then describes some of the more significant real-time sensors presented in the literature over the past 10 years or so.

Mentions: Deng et al. [30] presented a formaldehyde gas sensor based on an ammonium sulfate derivatization reagent and a capillary electrophoresis – electrochemical detection (CEED) system (see Figure 9). The reaction between the derivatization regent and formaldehyde was formulated as follows:(4)4NH4++6HCHO↹(CH2)6N4H++3H++6H2O.
