PurityPlus® EPA Protocol Specialty Gas Mixtures for Portland

Environmental worries might not be the news they once were, thanks to other, more urgent socio-political realities of the day – and to changing political priorities. But “out of sight” doesn’t mean “out of mind.” Industries and municipalities coast to coast and border to border are still mandated to calculate air pollution emissions and ambient air quality. And the resulting measurements do indeed still have both legal and economic consequences.
As long as calibrated instruments are used for measuring purposes, said instruments will require pure, stable, and precise mixtures of compressed specialty gases to guarantee complete accuracy. And Cryo-Source will be here in Portland to produce them – just as we’ve [[done from our earliest days.
The calibration gases we manufacture and distribute for environmental monitoring are those classified by the EPA, the National Institute of Standards and Technology (NIST), a variety of stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. In particular, we offer our Portland 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
Know that our production of these EPA Protocol Gases follows the harshest 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 employed for the most part, given their ability to lengthen the shelf life of these gases considerably
Assessing air pollution is still critical to the health and economic well-being of Portland. While that remains the case, Cryo-Source will be here to that assure the most accurate monitoring possible. If EPA compliance is important to the achievement of your goals, turn to Cryo-Source, your local PurityPlus® Partner, for every calibration gas requirement.
