New White Paper for SPECTRO MS: Isotope Ratios in Geochemistry

March 1, 2011

Origin and age determination of rock samples
SPECTRO MS is the first ICP mass spectrometer to simultaneously record the concentrations of 210 isotopes
Determination of isotope ratios in per mille ranges
Kleve, March 2011 – A new white paper dealing with isotope ratios in geochemistry for the simultaneously measuring SPECTRO MS ICP mass spectrometer is available from SPECTRO Analytical Instruments. The white paper, titled “Fully Simultaneous ICP-MS:  A New Approach to Isotope Geochemistry,” details ways geological laboratories can profit from isotope and element ratio analysis and designates the SPECTRO MS as a powerful, user-friendly and less-expensive alternative to multi-collector mass spectrometers.

The isotope ratios offer insight into the age and origin of rock samples and can be used to  determine the “fingerprint” of rock, mineral and ceramic samples. Rare earth metals are especially important geochemical indicators, whose relative presence helps establish conclusions as to tectonic environment and history.

“Until now simultaneous determination of isotope and element contents was only possible to a certain degree; making analyses both time consuming and expensive,“ explains Willi Barger, Product Manager for ICP-MS at SPECTRO. “The SPECTRO MS simultaneously records 210 isotope concentrations and ratios to four decimal places during every measurement and at a much lower cost than sequential mass spectrometers. “Detection limits for  the SPECTRO MS are in the low parts-per-trillion (ppt) range. In addition, the SPECTRO MS is easy to operate. Users obtain categorized, reproducible results with the press of a button.

White Paper Available Free-of-Charge
Users who want to find out more about using the SPECTRO MS for isotope and element ratio analysis in geochemistry will find a comprehensive description in the new white paper “Fully Simultaneous ICP-MS:  A New Approach to Isotope Geochemistry” that is available for free at The white paper is oriented not just towards geochemical laboratories but to other users as well: The SPECTRO MS is ideal for origin determination in the food industry, forensic science and other areas.

Background SPECTRO MS
Introduced in 2010, the SPECTRO MS is the world’s first fully simultaneously measuring mass spectrometer with inductively coupled plasma. With its novel Direct Charge Detector, the instrument simultaneously records 75 elements and their isotopes from lithium to uranium with every measurement. With a newly developed ion optic and double-focusing sector field mass spectrometer with Mattauch-Herzog geometry, the SPECTRO MS is able to deliver much more precise and reproducible results than conventional sequential mass spectrometers.
