In situ analysis of 230Th–232Th–238U ratios in titanite by fs-LA-MC-ICPMS

In situ analysis of 230Th–232Th–238U ratios in titanite by fs-LA-MC-ICPMS

Günther et al., J. Anal. At. Spectrom., 2012, Advance Article

In this paper former Chair of the Editorial Board Detlef Günther, J. M. Koornneef and colleagues in Switzerland and Germany, have been studying the the potential of femtosecond laser ablation multi-collector inductively coupled plasma mass spectrometry (fs-LA-MC-ICPMS) for in situ analysis of U–Th disequilibria in titanite. The determination of U-series isotope compositions are used in a wide range of geological materials such as carbonates, iron oxides, opal, and zircon.

Bromine and iodine determination in active pharmaceutical ingredients by ICP-MS

Bromine and iodine determination in active pharmaceutical ingredients by ICP-MS

Flores et al., J. Anal. At. Spectrom., 2012, Advance Article

And from our Advisory Board, Erico M. M. Flores from the Universidade Federal de Santa Maria, Brazil, and colleagues have been looking at a method based on microwave-induced combustion (MIC) and applied it to the digestion of active pharmaceutical ingredients. They used this to determine bromine and iodine by inductively coupled plasma mass spectrometry (ICP-MS). This test can be used to test for halogen impurities in pharmaceutical products.
