Abstract

The Palmes sampler is largely used to carry out indicative measurements for NO] as considered in EU legislation (Daughter Directive 1999/30/EC). In order to comply with the quality objectives set out in this directive it is important that the limits of this technique are fully appreciated. The sampler was tested in a chamber study and in field trials. Experiments were carried out to study the effect of wind turbulence, the stability of the NO2-TEA adduct and the self- consistency of the method. The results of these experiments demonstrated underestimation in comparison to chemiluminescence probably due to photodegradation of the NOi-TEA adduct and/or incomplete e
