Protocol Gases: What Are They? And Why Do They Cost More than a Certified Gas Standard?

The United States Environmental Protection Agency demands the use of Protocol Gases to set air pollution monitors. In the EPA’s view, deploying these gases “helps to ensure that air pollution measurements are accurate and can be trusted.”*

The protocol process was introduced by the EPA, NIST (the National Institute of Standards and Technology), and stakeholders including the auto industry and specialty gas manufacturers to better the accuracy and stability of calibration gases used for air monitoring equipment.

The EPA defines Protocol Gases as “compressed gases used to calibrate air pollution monitors for consistent and reliable monitoring.” Certified standards aren’t the only issue, though. Protocol Gases also require that the reported gas concentration must be traceable to NIST reference standards and formulated using the process as described in EPA protocol documentation. This process requires that specialty gas producers get hold of these reference gases for the protocol mixtures they market. Beyond the costs incurred buying this reference inventory and the time necessary to certify both the accuracy and stability of the gas, the EPA also requires that gas producers undergo an EPA-coordinated blind test to validate consistency and accuracy.

Coastal Welding Supply follows every applicable procedure to make certain that all of the protocol gases we supply our Beaumont customers meets or beats the procedure mandated in EPA Publication 600 (2012) and that the specific producing specialty gas laboratory is ISO 1705-compliant. Copies of the compliance documentation, including “round robin” reports, are always available on request. companyname’s got what you’re looking for. Just for the information and support you need.
