PurityPlus® EPA Protocol Specialty Gas Mixtures for Winona

Environmental issues might have taken a back seat in the news to other, more pressing socio-political crises – 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 obligated to measure air pollution emissions and ambient air quality. And the subsequent measurements very definitely still have legal, not to mention economic consequences.
As long as calibrated instruments are needed for measuring purposes, said instruments will call for pure, stable, and exact mixtures of compressed specialty gases to guarantee total accuracy. And Mississippi Welders Supply Co., Inc. will be here in Winona to produce them – just as we’ve been doing from our first 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), numerous stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. In particular, we offer our Winona 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
Keep in mind that our production of these EPA Protocol Gases abides by the most stringent EPA specifications and procedures. We then analyze the mixtures pursuant to NIST-traceable standards. Next, we observe cutting-edge cylinder preparation procedures, aluminum cylinders being employed for the most part, given their ability to lengthen the shelf life of these gases significantly
Analyzing air pollution is still vital to the health and economic well-being of Winona. That being the case, Mississippi Welders Supply Co., Inc. will be here to provide insure the most error-free monitoring possible.
