Bruker has introduced a complete solution to test and verify adherence to the International Maritime Organization (IMO) Low Sulfur Fuel Oil Standard Requirement in response to the significant reduction of the maximum permissible levels of sulfur in marine fuels from 3.5 % to 0.5 %, as being enforced from the beginning of 2020. The new MARPOL package is based on the portable CTX™ 500S XRF analyser, and includes a ready-to-go MARPOL calibration set-up, a quality control (QC) kit with sample cups, XRF safety foil and QC standards. The calibration set-up, specifically developed for MARPOL applications, enables the instrument to provide detection limits of 30 ppm (3σ) for sulfur, making it suitable for marine fuel testing at service labs, supply stations, on docks, in ports and aboard ships, even for the ultra-low 0.1 % sulfur limit which continues to be the standard in Emission Control Areas (ECA). Fuel samples can be placed inside the analysis chamber using sample cups or other liquid containers. All user operation is through an easy-to-use front panel touchscreen display or an optional PC via Wi-Fi or USB.
