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 ...
