PurityPlus® EPA Protocol Specialty Gas Mixtures for Indianapolis06/29/2018 Environmental matters may indeed 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 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), various stakeholders, and specialty gas producers like PurityPlus® as EPA Protocol Gases. In particular, we provision our Indianapolis customers with the following mixtures … Carbon Dioxide (CO2) in AirCarbon Dioxide (CO2) in Nitrogen (N2)Carbon Monoxide (CO) in AirCarbon Monoxide (CO) in Nitrogen (N2)Hydrogen Sulfide (H2S) in AirHydrogen Sulfide (H2S) in Nitrogen (N2)Methane (CH4) in AirMethane (CH4) in Nitrogen (N2)Nitric Oxide (NO) in AirNitric Oxide (NO) in Nitrogen (N2)NOx (Nitric Oxide and Nitrogen Dioxide) in AirNOx (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 abides by the harshest EPA specifications and procedures. We then analyze the mixtures in accordance with 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 appreciablyAssessing air pollution is still important to the health and economic well-being of our region. While that remains the case, American Welding & Gas, Inc. will be here to that assure the most perfect monitoring possible. If EPA compliance is important to the achievement of your goals, get hold of American Welding & Gas, Inc., your local PurityPlus® Partner, for all your calibration gas needs.
