Atomic Spectrometry Update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Previous Updates 84,85 have referred to the work of Michalke and colleagues in which concentrations of Se in paired serum and CSF specimens were compared to investigate whether there may be positive uptake into neural tissue. Following from the earlier studies, further work looking at Se 86 and Mn 87 in serum and CSF has been reported.…”

Atomic spectrometry update. Advances in atomic spectrometry and related techniques

“…[1][2][3][4][5] A critical approach to the selection of material has been adopted, with only novel developments in instrumentation, techniques and methodology being included. It covers atomic emission, absorption, fluorescence and mass spectrometry, but excludes material on speciation and coupled techniques which is included in a separate review.…”

Oxygenation Mechanism of Ions in Dynamic Reaction Cell ICP-MS

“…[6][7][8][9][10][11] In recent years, methods employing collision/reaction gas cells using He, H2, NH3, CH4, or O2 have been introduced into ICP-MS to remove the interferences of coexisting ions. [12][13][14][15][16] In particular, when He is used as the collision gas, spectral interferences caused by molecular ions are effectively reduced. All ions in the collision/reaction cell lose their kinetic energies in collision with He atoms, but molecular ions lose more kinetic energy than do elemental ions.…”
