Gaseous formaldehyde is one of the harmful and injurious VOCs (volatile organic compounds), and has been reported to develop Sick-house syndrome, especially at the hermetic house. In this work, we have constructed a high-sensitive NADH (λ=340nm) fluorometric biochemical-sniffer by incorporating fibre-optic device with UV-LED (λ=335nm) based excitation system and FALDH (formaldehyde dehydrogenase) enzyme membrane into a diaphragm reaction cell with gas- and liquid-compartments for the formaldehyde monitoring in the gas phase. The NADH fluorometric sensor...
