REAL-TIME MONITORING OF AIRBORNE FORMALDEHYDE CONCENTRATIONS BASED ON A MICROFLUIDIC ANALYTICAL DEVICE: APPLICATION TO FIELD MEASUREMENTS

Abstract : A new analytical method based on microfluidic device for formaldehyde detection was developed and patented. This 4 kg fully automatic instrument has a response time of 10 min, a temporal resolution of 2 seconds and a detection limit of 1 µg m-3. Our formaldehyde micro-analyser was then used for continuous monitoring during field campaigns in schools for several weeks. Our measurements were found to be in excellent agreement with those measured with the ISO 16000-3 reference method (active sampling on DNPH cartridges).
