Reported are the effects of easily ionizable concomitant elements on non-spectroscopic interferences in ICP-MS. Analyte ion suppression was studied for 7Li,...
Boron in fresh and saline waters was determined by inductively coupled plasma mass spectrometry (ICP-MS). The presence of concomitant elements in solution...
The effect of ion lens voltage settings and plasma conditions on nonspectroscopic interferences has been studied. The change in ion count rate for 7Li, 10B,...
The application of electrothermal vaporisation as a means of sample introduction for the determination of some of the platinum group metals by inductively...
A method for the determination of B isotope ratios In a variety of geological materials Is described. Boron isotope ratios are determined with a precision of...
Saline Ca-Na/Cl type groundwaters and brines sampled in deep mines over an extensive area of the Canadian Precambrian Shield have elevated BrCl ratios which...
Basinal strata spanning the Late Ordovician extinction have been determined for major and trace elements, and isotopes of C, O and S. A marked increase in...
Grain size separates of the Cretaceous-Tertiary (K-T) fireball layer at marine sites and the entire K-T boundary interval at nonmarine sites (fireball layer,...
This study presents the abundances of Ru, Ir, Pt, Pd, Rh, and Au (platinum-group elements; PGE) in the ejecta layer at the Cretaceous-Tertiary boundary and...
Ruthenium and Ir are the least mobile platinum group elements (PGEs) within the Cretaceous-Tertiary (K-T) boundary clay. The Ru/Ir ratio is therefore the most...
