Size distribution of particulate matter in exhaust gases in inductively coupled plasma atomic emission spectrometry

Abstract

An examination was made of the size of particulate matter in ICP-AES exhausts with the objective of defining the filtration requirements for glove-box installation. Using inactive simulants it was shown that >75% of the material is of sub-micrometre size with a median diameter in the range 0.1–0.2 µm. The presence of other elements does not alter significantly the size distribution of the major constituent.
