Abstract

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been gaining increasing attention as a method for the analysis of solid samples. This technique has the advantage of little or no sample preparation, and in particular there is no need for acid digestion. In this paper, LA-ICP-MS is applied to investigate the homogeneity of small aerosol filter sections. Lines of approx. 3 cm length are scanned with a Nd-YAG laser and the ablated material is analysed by ICP-MS. Tests investigate whether the precision of LA-ICP-MS is sufficient to detect the inhomogeneity of the deposit on different filter materials. These results are compared to those obtained with methods such as GF-AAS and PIXE. Other studies include optimisation and comparison of element analysis of aerosols sampled on quartz fibre filters. Results obtained are compared to those from ICP-AES and GF-AAS determinations using acid digested samples.
