Spectral Insights into Diesel Quality
The Raman spectra of conventional low-sulfur diesel and ultra-low-sulfur diesel (ULSD) reveal the analyzer’s ability to distinguish subtle compositional differences. Specific spectral bands, highlighted with downward arrows in the figure, are prominent in the low-sulfur diesel sample but absent in the ULSD sample. These spectral distinctions allow Raman technology to accurately quantify sulfur content and other critical parameters, even at trace levels required for ULSD compliance.
ASTM-Validated Analysis
HORIBA’s Raman analyzers are calibrated to align with ASTM methods for laboratory analysis, ensuring consistency and comparability with industry-standard procedures. By bridging the gap between laboratory accuracy and online real-time monitoring, our Raman technology enhances process control, reduces the need for frequent sampling, and minimizes operational costs.
With its advanced capabilities, HORIBA Raman technology equips refineries with the tools needed to optimize diesel production, maintain compliance, and improve overall efficiency—all while ensuring reliable and accurate measurement of key fuel properties.
