Bruker’s CTX — our self-contained, portable ED-XRF (energy dispersive XRF) spectrometer – is ideal for screening sulfur (sulphur) levels in fuel oil (petroleum). Please contact our product team for more information on how the CTX can serve your sulfur analysis needs.
Acceptable sulfur levels in fuel oil are strictly regulated for environmental reasons, with high penalties for non-compliance. Sea vessels routinely require proof that fuel oil meets the existing norms, in particular the 0.10% m/m sulfur standard requirement imposed by MARPOL’s Annex VI, Regulation 14. It is the responsibility of ship and barge owners to comply. Moreover, compliance matters to fuel inspectors, bunker suppliers, ship operators, and time charters. It is typical of maritime authorities — the enforcers of the regulation — to require a “MARPOL sample” as a part of inspections. In some cases, especially in Emission Control Areas, additional samples are often taken from the engine feed or returning line, in order to verify the active fuel’s compliance.
The existing standards require the use of EDXRF for sulfur screening, namely:
- ISO 8754-2003 (“Petroleum products -- Determination of Sulfur Content -- Energy-Dispersive X-ray Fluorescence (EDXRF) Spectrometry”)
- ASTM D4249 (“Standard Test Method for Sulfur in Petroleum and Petroleum Products by EDXRF Spectrometry”).
Inspectors, bunker suppliers, engineers, and ship staff performing fuel screening and inspections need a convenient analyzer capable of accurate and reproducible sulfur readings, regardless of where or by whom the measurements are taken. Buker’s CTX is the exemplary tool of choice for the job and performs it quickly and easily. Under factory calibration, it measures up to 1000 ppm (0.1%) sulfur, with an error less than ± 100 ppm sulfur, in 30-60 seconds, with a limit of detection (LOD) of 30ppm (3σ) and a limit of quantification (LOQ) of 100ppm (10σ).
Ideal for use in service labs, at supply stations, on docks, in ports, and even on board, the CTX portable, countertop analyzer can be used to:
