PurityPlus® EPA Protocol Specialty Gas Mixtures

Environmental concerns may well have taken a back seat in the news to other, more pressing socio-political realities of the day – and to changing political priorities. But “out of sight” doesn’t mean “out of mind.” Industries and municipalities across the United States are still required to measure air pollution emissions and ambient air quality. And the resultant measurements do indeed still have legal as well as economic ramifications.
 As long as calibrated instruments are used to do the measuring, such instruments will require pure, stable, and precise mixtures of compressed specialty gases to assure complete accuracy. And PurityPlus® will be here to provide them – just as we and our more than 150 Partners at 600 North American locations have been doing from our earliest days.
 The calibration gases we produce and distribute for environmental monitoring are those established by the EPA, the National Institute of Standards and Technology (NIST), various stakeholders, and specialty gas producers like us as EPA Protocol Gases. Specifically, we offer the following mixtures …
  • Carbon Dioxide (CO2) in Air
  • Carbon Dioxide (CO2) in Nitrogen (N2)
  • Carbon Monoxide (CO) in Air
  • Carbon Monoxide (CO) in Nitrogen (N2)
  • Hydrogen Sulfide (H2S) in Air
  • Hydrogen Sulfide (H2S) in Nitrogen (N2)
  • Methane (CH4) in Air
  • Methane (CH4) in Nitrogen (N2)
  • Nitric Oxide (NO) in Air
  • Nitric Oxide (NO) in Nitrogen (N2)
  • NOx (Nitric Oxide and Nitrogen Dioxide) in Air
  • NOx (Nitric Oxide and Nitrogen Dioxide) in Nitrogen (N2)
  • Oxygen (O2) in Nitrogen (N2)
  • Propane (C3H8) in Air
 Rest assured, our production of these EPA Protocol Gases adheres to the strictest EPA specifications and procedures. We then analyze the mixtures in accordance with NIST-traceable standards. Next, we follow the most advanced cylinder preparation procedures, aluminum cylinders being used most often, given their ability to extend the shelf life of these gases significantly.
Monitoring air pollution is still vital to the health and economic well-being of our country. As long as that’s the case, PurityPlus and its vast network of specialty gas Partners will be here to supply the EPA Protocol specialty gas mixtures needed to ensure the most accurate monitoring possible. If EPA compliance is important to your enterprise, call on your nearest PurityPlus® Partner for all your calibration gases.
