Unrivaled speed and precision for dissolved gas measurements

 Instruments in 13 Countries

The Bay Instruments membrane inlet mass spectrometer (MIMS) is the de facto standard for denitrification studies which demand the highest precision for N₂ and N₂/Ar ratios.  Our MIMS is the instrument of choice for government and academic researchers, oceanographers, and environmental scientists who require precise measurements of dissolved gases in water. Our applications have grown over the last 25+ years to encompass denitrification, ecosystem oxygen studies, trace environmental gases, and stable isotope studies. Our MIMS provides high precision, rapid analysis, and small sample size capabilities with a small footprint that makes it an excellent candidate for field applications.
