PurityPlus® EPA Protocol Specialty Gas Mixtures for Minneapolis

Environmental matters might been superseded in the news by other, more pressing socil-political realities of the day – and by changing political priorities. But “gone” does not mean “forgotten.” Industries and municipalities nationwide are still obligated to keep tabs on air pollution emissions and ambient air quality. And the subsequent measurements do most assuredly still have legal, not to mention economic implications.
As long as calibrated instruments are needed for measuring purposes, said instruments will necessitate pure, stable, and precise mixtures of compressed specialty gases to guarantee total accuracy. And Toll Company will be here in Minneapolis to deliver them – just as we’ve been doing from the day we first opened our doors.
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 variety of stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. Specifically, we supply our Minneapolis 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
Understand that our production of these EPA Protocol Gases follows the most stringent EPA specifications and procedures. We then analyze the mixtures in accordance with NIST-traceable standards. Next, we stick to the most advanced cylinder preparation procedures, aluminum cylinders being used predominantly, given their ability to prolong the shelf life of these gases markedly
Monitoring air pollution is still critical to the health and economic well-being of Minneapolis. While that remains the case, Toll Company will be here to deemed best to insure the most accurate monitoring possible. If EPA compliance is important to the achievement of your goals, get hold of Toll Company, your local PurityPlus® Partner, for every calibration gas necessity.
