In situ Rb-Sr dating by collision cell, multicollection inductively-coupled plasma mass-spectrometry with pre-cell mass-filter, (CC-MC-ICPMS/MS).

We document the utility for in situ Rb-Sr dating of a one-of-a-kind tribrid mass spectrometer, ‘Proteus’, coupled to a UV laser ablation system. Proteus combines a pre-cell quadrupole mass-filter,collision cell,...

High-precision analysis of potassium isotopes by MC-ICP-MS without collision cell using cool plasma technique in low resolution mode

This study presents a method for high-precision stable potassium (K) isotope analysis using Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS) without collision cell in low resolution mode. Cold plasma technique...

Potassium isotopic composition of 7 widely available biological standards using collision cell (CC)-MC-ICP-MS.

The development of collision-cell multi-collection inductively-coupled-plasma mass-spectrometers has revolutionized K isotope geochemistry, improving the sensitivity by over a factor 10 compared to older generation instruments. The application of isotope geochemistry...

Attenuation of doubly charged ion interferences on arsenic and selenium by ICP-MS under low kinetic energy collision cell conditions with hydrogen cell gas

A collision cell with hydrogen gas in place of the widely used helium attenuates not only polyatomic ion interference but also doubly charged ion interference by using KED.
