PurityPlus® EPA Protocol Specialty Gas Mixtures

Environmental worries might have taken a back seat in the news to other, more pressing socio-political realities of the day – and to changing political priorities. But what’s unseen isn’t necessarily unnecessary. Industries and municipalities coast to coast and border to border are still mandated to measure air pollution emissions and ambient air quality. And the resultant measurements do indeed still have both legal and economic consequences.
As long as calibrated instruments are used for measuring purposes, such instruments will have to have pure, stable, and precise mixtures of compressed specialty gases to guarantee absolute accuracy. And Arc3 Gases will be here to produce them – just as we’ve done from our earliest days.
The calibration gases we mix and distribute for environmental monitoring are those designated by the EPA, the National Institute of Standards and Technology (NIST), various stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. To be specific, we offer our customers 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 most demanding EPA specifications and procedures. We then analyze the mixtures pursuant to NIST-traceable standards. Next, we observe state-of-the-art cylinder preparation procedures, aluminum cylinders being used for the most part, given their ability to lengthen the shelf life of these gases markedly
Analyzing air pollution is still important to the health and economic well-being of our area. While that remains the case, Arc3 Gases will be here to deliver]79] the EPA Protocol specialty gas mixtures needed to ensure the most accurate monitoring possible. If EPA compliance is important to your activities, call on Arc3 Gases, your local PurityPlus® Partner, for every calibration gas need.
