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.

Amplify your precision with 1013 amplifier technology

Are you limited in sample size? One of the major challenges in geosciences is the analysis of small ion beams. The analytical precision of these studies is limited by the detection system of your mass spectrometer. Equipped with 1013 ohm amplifiers with a new resistor design, our spectrometers enable you to get faster response times and extremely low noise/signal characteristics.

Analysis without compromise

The patented Emission Suppression Technology (EST) revolutionizes noble gas isotope ratio mass spectrometry by switching off ionization whilst the sample is equilibrating in the source. This removes the trade-off between sample equilibration and precision.
