Empa utilizes Axetris mass flow controllers (MFCs) in its research laboratory at the 'Top of Europe.'
Swiss Federal Laboratories for Materials Science and Technology (Empa) currently use Axetris mass flow controllers (MFCs) in its research laboratory at the Jungfraujoch High Altitude Research Station, located at the “Top of Europe.” Axetris MFCs were chosen to fulfill the strict demands of repeatability and stability for enabling high-performance isotope tracking using laser spectroscopy.
CO2 isotope tracking to study climate change
The study of CO2 isotopes provides valuable information about the effects of CO2 generated due to human activities on climate change and global warming. Traditionally, various mass spectrometric techniques, such as Isotope Ratio Mass Spectrometry (IRMS), have been used to study CO2 isotopes in order to classify emission sources.
Since late 2008, Empa is operating an isotope spectrometer, based on a quantum cascade laser (QCL), at the high-altitude research station located on Jungfraujoch in the Bernese Oberland region of Switzerland. The research station is situated on the famous Swiss peak at an altitude of 3580 msl, at the so-called “Sphinx Observatory.”
