Abstract

Determination of Light Elements in Marine Aerosols by Grazing-Emission X-Ray Fluorescence A contribution to subproject AEROSOL Martina Schmeling and Rene Van Grieken Department of Chemistry, University of Antwerp, Universiteitsplein 1, B-2610 Antwerp, Belgium For the determination of light elements in aerosol samples, the grazing- emission X-ray fluorescence technique (GEXRF) was applied. This wave- length dispersive technique has been used before only for the determination of light elements in wafers (de Bokx et aL, 1995, de Bokx et al, 1997) and aqueous samples (Claes et al, 1997). This contribution describes the adaption of this technique for the analysis of aerosols with special emphasis to marine aerosols and considers critically its main features. Marine aerosols were collected for this purpose during a measuring campaign in November 1997 over the North Sea with a 5-stage Battelle impactor. T
