We offer full integration capabilities to install in a sample system and provide field service support. 

Why Mass Spectrometry?

Mass Spectrometry is an analytical tool useful for measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample.  These measurements can often be used to calculate the exact molecular weight of the sample components as well. Typically, mass spectrometers can be used to identify unknown compounds via molecular weight determination, quantify known compounds, and determine molecules’ structure and chemical properties.


Mass Spectrometry has many advantages over conventional GC and Calorimeter Instruments to ensure your facility is in compliance with 40 CFR Part 60 and Part 63

  • Fast response time: ~ 20 seconds per analyte

  • Flexibility in adding applications in the future

  • Capable of measuring a variety of applications on ONE Mass Spec saving your facility on costs

  • Measures various streams on one analyzer saving your facility money

  • High sensitivity: ppm/ppb levels

  • Linear through the entire measuring range which allows you to use low concentration standards for calibrations providing safety to your plant and crew
