PurityPlus® EPA Protocol Specialty Gas Mixtures for Western Michigan

Environmental worries might have taken a back seat in the news to other, more urgent socio-political demands – and to changing political priorities. But “gone” does not mean “forgotten.” Industries and municipalities across the United States are still required to measure air pollution emissions and ambient air quality. And the subsequent measurements very definitely still have legal, not to mention economic ramifications.
As long as calibrated instruments are needed to take measurements, said instruments will call for pure, stable, and precise mixtures of compressed specialty gases to ensure complete accuracy. And GTW will be here in Western Michigan to produce them – just as we’ve been doing from the day we first opened our doors.
The calibration gases we produce 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. To be specific, we offer our Western Michigan 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 follow the latest cylinder preparation procedures, aluminum cylinders being used for the most part, given their ability to lengthen the shelf life of these gases markedly
Keeping tabs on air pollution is still essential to the health and economic well-being of Western Michigan. While that remains the case, GTW will be here to deliver]79] the EPA Protocol specialty gas mixtures {{needed to ensure the most perfect monitoring possible. If EPA compliance is important to your activities, look to GTW, your local PurityPlus® Partner, for all your calibration gas needs.
