Direct, multielement determinations from cotton swipes via plate express microextraction coupled to an inductively coupled plasma mass spectrometer (μEx-ICP-MS)

Abstract

Use of a microextraction device allows for ready sampling of solid substrates, such as cotton swipes, allowing transfer of sub-microgram quantities for multielement ICP-MS analysis.

Mapping of uranium particles on J-type swipes with microextraction-ICP-MS

“…9 The initial motivation for microextraction-ICP-MS was to eliminate bulk sample digestion, which can be a time consuming process, and instead directly sample the surface for the analysis of uranium, 7 plutonium, 10,11 and other trace elements. 12 Subsequent efforts explored extraction of solid uranium particulates from the surface, 13 with rapid isotopic determination.…”
