Dual-column capillary microextraction combined with ETV-ICP-MS for the speciation of arsenic in human hair extracts
Date: Mar 1, 2010
Author:
A dual-column capillary microextraction was developed for the sequential separation/preconcentration of arsenite, arsenate, monomethylarsonic acid and dimethylarsinic acid in extracts of human hair followed by electrothermal vaporization inductively coupled plasma mass spectrometry detection with iridium as permanent modifier.

Flame atomic absorption spectrometry (FAAS) can be used effectively as an alternative method for the determination of calcium and magnesium ions in biodiesel and fuels derived from vegetable oil, according to researchers in Brazil. The technique precludes certain preparative steps and avoids the need for some toxic organic solvents.

Metallic environmental mops
Date: Nov 15, 2009
Author: David Bradley
Inductively coupled plasma spectroscopy and mass spectrometry revealed that natural metal chelators, so-called siderophores, which are produced by bacteria and plants, make much better absorbers of cadmium, and potentially other toxic metals, than synthetic EDTA, and so could improve the efficiency of phytoremediatioon systems.
