The system consists of a scrubber coil for enrichment of the analyte from air in an aqueous solution and a directly connected fluorescence detector. Because of using a reagent solution containing alcohol dehydrogenase (ADH) and nicotinamide adenine dinucleotide (NAD+) for absorption, ethanol can react directly with ADH and NAD+ during air sampling, producing NADH, which can be measured by fluorescence detection. The influence of reagent concentrations, gas flow rate and scrubber solution flow rate on the performance of the instrument was tested. Possible ozone interferences can be avoided by placing a KI coated filter in front of the scrubber inlet. The response time of the system was found to be 2.3 min and the detection limit about 1 ppbV. The applicability of the developed method was demonstrated during a field campaign in Brazil.Submitted by Texeira Ana (atanateixeira@gmail.com) on 2012-12-17T14:33:52Z No. of bitstreams: 1 Voigt.pdf: 188366 bytes, checksum: 99b28ddf6920ba702af4d5cd4b336670 (MD5)Made available in DSpace on 2012-12-17T14:33:52Z (GMT).
