What is noble gas mass spectrometry?

Noble gas mass spectrometry studies isotopes of noble gases helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe). These gases are found in very small quantities in a variety of environmental samples and the study of the isotopes of these noble gases provides powerful insights in the fields of geochronology, cosmochemistry, and thermochronology.

Isotope ratio analysis of the small samples of noble gases require static vacuum, low-volume, high-resolution instrumentation. The three Thermo Scientific noble gas mass spectrometers are designed to meet these requirements.

Whether for Ar-Ar dating, where sensitivity and multicollection is key, or for high precise He isotope analysis requiring low abundance sensitivity, or for simultaneous interference-free measurement of all noble gases, where ultimate high-resolution variable multicollection is mandatory, our Noble Gas Portfolio covers it all.

We also offer a noble gas preparation system, to provide a source of clean noble gases (helium, neon, argon, krypton, and xenon) for analysis.
