PurityPlus® EPA Protocol Specialty Gas Mixtures for Sioux Falls

 
Environmental matters might been replaced in the news by other, more urgent socil-political crises – and by changing political priorities. But “out of sight” doesn’t mean “out of mind.” Industries and municipalities across the United States are still mandated to measure air pollution emissions and ambient air quality. And the resulting measurements do indeed still have legal, not to mention economic ramifications.
As long as calibrated instruments are used to take measurements, said instruments will require pure, stable, and precise mixtures of compressed specialty gases to ensure total accuracy. And A-OX Welding Supply will be here in Sioux Falls to provide them – just as we’ve been trusted to do from our first 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 on the order of PurityPlus® as EPA Protocol Gases. Specifically, we provide our Sioux Falls customers with 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
To be sure, our production of these EPA Protocol Gases complies with the most uncompromising EPA specifications and procedures. We then analyze the mixtures in accordance with NIST-traceable standards. Next, we stick to state-of-the-art cylinder preparation procedures, aluminum cylinders being used most often, given their ability to extend the shelf life of these gases markedly
Assessing air pollution is still vital to the health and economic well-being of our region. While that remains the case, A-OX Welding Supply will be here to produce and distribute assure the most perfect monitoring possible. If EPA compliance is important to the achievement of your goals, call on A-OX Welding Supply, your local PurityPlus® Partner, for every calibration gas need.
