For those in the energy industry, EPA protocol gases are an indispensable component of any successful operation. However, there are a number of common challenges associated with these gases, such as cylinder shelf life, onsite inventory, compliance, and cost control. Having the right EPA protocol gas supplier in California can not only overcome these challenges, but can also help you to find new opportunities to become more effective, efficient, and productive in your daily business. When choosing a supplier of EPA protocol gases, be sure to choose one that is able to provide:

  • Accurate calibration standards 
  • Exact concentration ranges 
  • Simple and comprehensive cylinder management
  • Online ordering and access to Certificates of Analysis (COAs) and expiration information
  • Technical expertise
  • NIST traceability
  • Low-level single- and multi-component mixtures

How to achieve accurate calibration standards 

All of our EPA protocol gases are made in strict accordance with EPA protocols such as the EPA Traceability Protocol for Assay and Certification of Gaseous Calibration Standards EPA 600/R-12/531, May 2012.  We’re able to do so at our ISO/IEC 17025 accredited laboratory and gas facility in Anaheim, California.


Our Anaheim laboratory enables us to demonstrate traceability to standards from the National Institute of Standards and Technology (NIST) and for all of our EPA protocol gases. We offer to maintain a customized stocked inventory of any standard EPA emission calibration gases based on customer’s requirements.  We can also blend custom gas mixtures to meet just about any application. Some of the most common uses for our EPA protocol gases include:

  • Environmental auditing
  • Ambient monitor calibration
  • Certification of CEM systems
  • Relative Accuracy Test Audits (RATA tests)
  • Scrubber efficiency verification
  • Cylinder Gas Audits (CGAs)
  • Linearity checks
  • Stack monitor calibration
