"Calibration error, and the resultant CEM inaccuracy, is costing utilities and other companies millions of dollars each year," explains Robert Davis, Senior Environmental Products Manager for Scott Specialty Gases. "Suppose a utility emits 100,000 tons of SO2 and is using a protocol with a 2% analytical uncertainty allowed by EPA. That uncertainty could result in calibrating a CEM on the high side, resulting in overstating emissions by as much as 2%. If you consider a current market value of about $875/ton, the consequence of such an overstatement is a loss of $1,750,000 worth of emission allowances that the utility could otherwise bank or sell." Davis continues, "So eliminating uncertainty of the calibration gas is the key to more accurate emissions measurement. The closer you get to calibrating a CEM with a protocol gas mixture whose contents are known in absolute terms, the closer you get to measuring your emissions with precision. Our new Emissions Credit Class protocols do that job better than any other product available."

Laboratory analytical instrumentation, reference material, blend method, cylinder preparation, raw material quality, ambient production environment and other factors all combine to affect the integrity of EPA protocol gases. As the world's largest and most experienced producer of EPA protocols, only Scott Specialty Gases consistently demonstrates the ability to accurately interpret the mathematics of analytical uncertainties, and control the many variable dynamics involved when preparing high-accuracy calibration gases. Scott maintains the world's most extensive inventory of low-uncertainty Standard and NIST-Traceable Reference Materials (SRMs and NTRMs) which, when combined with recent scientific advancements in analytical technology, enable the company to achieve the strict linearity, sensitivity and reproducibility necessary to significantly reduce uncertainty of analysis when preparing gas mixtures. Emissions Credit Class Gold Standard EPA Protocols join Scott's highly acclaimed RATA Class protocols that provide guaranteed 1% analytical accuracy.

Scott Specialty Gases is the sole-source producer of gaseous SRM candidates for NIST and is a worldwide supplier of pure and mixed gases. Applications include natural gas, environmental, homeland security, laboratory, industrial, petrochemical, medical and semiconductor. Scott maintains numerous manufacturing facilities in both the U.S. and Europe.
