Specializing in High Precision Membrane Inlet Mass Spectrometers

Unrivaled speed and precision for dissolved gas measurements
Instruments in 15 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 20+ years to encompass denitrificaiton, ecosystem oxygen studies, trace environmental gases, and stable isotope studies. The MIMS provides high precision, rapid analysis, and small sample size capabilities with a small footprint that makes it an excellent candidate for field applications.
