EPA Protocol Rush

consistent accuracy and precision in emissions monitoring

Praxair's ProSpec™ EPA protocol and emissions monitoring calibration gases deliver stability, precision and accuracy.


Flaws in the calibration gas can result in productivity losses and other complications. Praxair's ProSpec EPA Protocol and Emissions Monitoring Gases can help you avoid rework, virtually eliminate time spent dealing with reference peak height drift, reduce wasted gas and simplify your inventory management.

With Praxair, you can enjoy consistent mixture accuracy and precision that reduces cylinder-to-cylinder variability. Our long shelf life and mixture stability mean you can use the gas for longer periods of time and have fewer concerns about inventory expiration. The stability also cuts down on reference peak height drift. All in all, your instrument calibration is just plain simpler to do.


By investing in the quality of our products and using a proprietary process that pays strict attention to detail in four critical areas, we can consistently provide accurate, precise and stable gases.

  • Qualifying and purifying raw materials
  • Proprietary cylinder preparation
  • Gravimetric fill and automated dynamic blending of mixtures
  • Quality control plus a suite of NIST SRMS / NTRMs
