Isotope Ratio Measurements for Sample Dating Studies Using Multicollector ICP-MS and Signal Enhancement via a Desolvating Nebulizer Accessory with Nitrogen Gas Addition

Multicollector ICP-MS instruments are widely used in geochemistry for high precision isotope ratio measurements. Isotope signal enhancement and/or mass spectral interference reduction (ex. oxides and hydrides from any injected water) is often necessary for useful measurement of low abundant isotopes and mass-limited samples.This work will describe the setup, optimization, and use of an advanced ...

Core Sampler

In addition to ordinary percussion gouges it is possible to apply a core sampler with a synthetic sampling tube or foil liners. These are transparent to facilitate immediate visual inspection in the field. The special cutting head has been fitted with an exchangeable core catcher in order to avoid loss of sample or sample contamination. The undisturbed sample can be sealed for transport to a ...
