Abstract

A fast method for the measurement of sub-ppb levels of naphthalene in ambient air is presented. Ambient air samples are collected by pumping air (2 or 3 litres) through adsorbent tubes filled with Tenax-TA. Analysis is performed by thermal desorption and cryofocusing, followed by capillary gas chromatography and mass spectrometric detection. The limit of detection is 0.1 ng of napthalene; recoveries based on thermally desorbed napthalene reached nearly 100 %. Up to 45 minutes are required for sampling and analysis of napthalene in air; this allows application of the procedure for monitoring this compound in urban and (due to the low limit of detection) in rural areas.
