PurityPlus® EPA Protocol Specialty Gas Mixtures for Fresno

Environmental matters may well been overtaken in the news by other, more urgent socil-political exigencies – and by changing political priorities. But what’s hidden isn’t necessarily harmless Industries and municipalities coast to coast and border to border are still required to calculate air pollution emissions and ambient air quality. And the subsequent measurements very definitely still have legal as well as economic implications.
As long as calibrated instruments are needed to get measurements, such instruments will require pure, stable, and precise mixtures of compressed specialty gases to guarantee absolute accuracy. And Fresno Oxygen & Welding Supplies/Barnes Welding Supply will be here in Fresno to deliver them – just as we’ve [[done from the day we first opened our doors.
The calibration gases we manufacture and distribute for environmental monitoring are those classified by the EPA, the National Institute of Standards and Technology (NIST), a number of stakeholders, and specialty gas producers on the order of PurityPlus® as EPA Protocol Gases. In particular, we supply our Fresno 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 complies with the toughest EPA specifications and procedures. We then analyze the mixtures according to NIST-traceable standards. Next, we follow state-of-the-art cylinder preparation procedures, aluminum cylinders being employed most often, given their ability to extend the shelf life of these gases appreciably
Measuring air pollution is still critical to the health and economic well-being of Fresno. That being the case, Fresno Oxygen & Welding Supplies/Barnes Welding Supply will be here to that assure the most perfect monitoring possible.
