Scott Low NOx EPA Protocol Gases
Concentrations as Low as 0.1 ppm for RATA Applications
Scott Brand Low NOx EPA Protocol Gases from Air Liquide are unique in the environmental industry. With guaranteed ±1% accuracy in concentrations as low as 0.1 ppm, they provide the highest reliability and level of confidence for meeting environmental compliance requirements. They are invaluable for use by stack testers and utilities, and can be used for Relative Accuracy Test Audits (RATAs).
Benefits and Features
- NIST or VSL-traceable.
- ±1% guaranteed dual-analyzed accuracy.
- Detailed Certificate of Accuracy meets EPA requirements.
- Identification of reference standard.
- Certified for NO, NOx, or both.
- Interference-Free multi-component mixtures are also available with either CO or CO2 certified.
Scott Low NOx EPA Protocol Gases are dual-analyzed using EPA G1 or G2 methods. Two independent analyses are performed after the blending process has been completed in order to determine the concentration for each component. As per EPA requirements, the values obtained from these analyses must agree to within ±1%. Air Liquide also manufactures Interference-Free™ Low NOx EPA Protocols with CO or CO2, creating the only dual-component low NOx protocol gas available today.
