PurityPlus® EPA Protocol Specialty Gas Mixtures for St. Louis

Environmental worries may well not be the news they once were, thanks 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 coast to coast and border to border are still mandated to calculate air pollution emissions and ambient air quality. And the subsequent measurements do most assuredly still have both legal and economic consequences.
As long as calibrated instruments are employed to accomplish the measuring, these instruments will require pure, stable, and precise mixtures of compressed specialty gases to ensure total accuracy. And Cee Kay Supply, Inc. will be here in St. Louis to deliver them – just as we’ve been trusted to do from our first days.
The calibration gases we manufacture and distribute for environmental monitoring are those identified by the EPA, the National Institute of Standards and Technology (NIST), a number of stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. In particular, we offer our St. Louis 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
Understand that our production of these EPA Protocol Gases abides by the strictest EPA specifications and procedures. We then analyze the mixtures in accordance with NIST-traceable standards. Next, we observe the most progressive cylinder preparation procedures, aluminum cylinders being employed primarily, given their ability to prolong the shelf life of these gases considerably
Keeping track of air pollution is still important to the health and economic well-being of our region. As long as that’s the case, Cee Kay Supply, Inc. will be here to that assure the most perfect monitoring possible. If EPA compliance is important to the fulfillment of your goals, call on Cee Kay Supply, Inc., your local PurityPlus® Partner, for every calibration gas need.
