Mercury methylation potentials in sediments an ancient cypress wetland using species-specific isotope dilution-GC-ICP-MS: Analytical method development and the effect of sorbent amendments
… inductively coupled plasma mass spectrometry (ICP-MS) with online sample ashing. The method combines a direct mercury analyzer (DMA) that is based on sample combustion, Hg pre-concentration by amalgamation with gold, and atomic absorption spectrometry (AAS), with a high resolution ICP-MS. …

A study of potentially toxic elements in the Forth and Clyde Canal, Scotland, UK
… mg/kg), and Zn (288 - 3640 mg/kg), measured by ICP-MS, were lower than those reported by British Waterways in 1992 but higher than relevant environmental quality standards, as was the Hg concentration (0.589 - 9.19 mg/kg) determined using CVAFS. The concentration of Fe was relatively constant, …

Speciation of Mercury by Chromatography Coupled with Atomic Spectrometry
A commercial GC-AFS instrument has been developed and optimised for the speciation of organomercury. This instrument couples a GC oven to a modified atomic fluorescence detector via a ceramic pyrolyser. Organomercury compounds in dichloromethane solvent were directly injected through a Programmable …
