May 2019 – New Whiteboard Video on Noble Gas Mass Spectrometry

Have you ever asked yourself how we can tell when the dinosaurs went extinct? The answers lie in the noble gas argon.


When lava cools, it hardens and the trapped potassium decays very slowly to argon. Today, scientists can measure the new argon that is trapped inside, along with its isotopes. Noble gas mass spectrometry analyses the isotopes of all five noble gases: with low volume, beam deflection multicollector array and 1013 Ohm Amplifier Technology. This array of technology offers unparalleled accuracy and precision. The lower the volume, the higher the sensitivity.
