The ultimate mass spectrometers for geochronology

The ultimate mass spectrometers for geochronology

Thermo Fisher Scientific has worked with geoscientists for decades, helping them to gain insights into the age of valuable rocks, minerals, sediments, and fossils. Our ICP-MS systems are workhorses for producing the highest quality age data from analyzing isotope systems of Rb-Sr, Sm-Nd, Re-Os, and Pb-U, and our noble gas mass spectrometers are the ultimate choice for obtaining the high precision Ar-Ar isotope ratio, cosmogenic exposure neon, and low temperature thermochronology data.
