PurityPlus® EPA Protocol Specialty Gas Mixtures for Indianapolis

Environmental matters may well have taken a back seat in the news to other, more urgent socio-political demands – and to changing political priorities. But “out of sight” doesn’t mean “out of mind.” Industries and municipalities nationwide are still required to monitor air pollution emissions and ambient air quality. And the resultant measurements very definitely still have legal, not to mention economic consequences.
As long as calibrated instruments are employed to get measurements, said instruments will require pure, stable, and flawless mixtures of compressed specialty gases to guarantee absolute accuracy. And American Welding & Gas, Inc. will be here in Indianapolis to provide 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 such as PurityPlus® as EPA Protocol Gases. In particular, we provision our Indianapolis 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
To be sure, our production of these EPA Protocol Gases abides by the harshest EPA specifications and procedures. We then analyze the mixtures pursuant to NIST-traceable standards. Next, we stick to the most progressive cylinder preparation procedures, aluminum cylinders being employed most often, given their ability to lengthen the shelf life of these gases appreciably
Assessing air pollution is still important to the health and economic well-being of Indianapolis. While that remains the case, American Welding & Gas, Inc. will be here to that assure the most perfect monitoring possible.
