Abstract:
Laboratories frequently face challenges to keep sulfur measurement instrumentation compliant with regulatory requirements of EPA 40 CFR Part 1090 Subpart N and ASTM D6299 standard established to demonstrate and monitor the proficiency of analytical measurement systems. These include refinery labs, third-party and any other laboratories measuring certain fuel parameters such as sulfur. Even after qualifying an instrument using the alternate procedure defined by the ASTM D5453 UV fluorescence method, maintaining long-term stability becomes difficult due to the characteristic nature of the measurement itself. These systems rely on an excitation sources that are inherently unstable over time, which subsequently affect analysis results. Excimer UV fluorescence technology offers increased stability thereby reducing required intervention to maintain analytical results within control limits. Science behind the benefits of the technology will be discussed, as well as data showing examples of violations and corrective actions taken.
