Abstract

A sensitive and selective method was developed for the determination of acrolein in ambient air by using liquid chromatography/tandem-mass spectrometry (LC/MS/MS). Air was sampled by passing through an O-(4-cyano-2-ethoxbenzyl) hydroxylamine (CNET) cartridge for 2∼24 hrs at a constant flow rate (200 mL/min). The acrolein-CNET derivative eluted from the cartridge with acetonitrile was separated by a reversed phase liquid chromatography and determined by LC/MS/MS in turbo spray ionization (ESI) positive mode. The collection efficiency of acrolein on a CNET cartridge was more than 99 %. The method detection limit was 0.4 ng/m³ in case of sampling volume of 0.3 m³ and relative standard deviation of repeated analysis was 5.0 %. Recoveries of acrolein on CNET cartridges under the condition of the relative humidity of 30∼87 % at the temperature of 25∼35 °C were 82∼92 %. In a refrigerator, acrolein-CNET derivative was stable for about 5 days on the cartridge, and that in the solution eluted with acetonitrile was stable for one month.<BR>This method was applied to the determination of ambient acrolein concentration for every 2∼3 hrs during one day. The concentrations of acrolein observed were in the range of 69∼288 ng/m³.
