SLFA-60

X-ray Fluorescence Sulfur-in-Oil Analyzer

HORIBA introduces the new standard of transportable sulfur-in-oil analyzers, the SLFA-60. This instrument introduces new software and hardware features to meet the growing changes in the petroleum industry. The instrument has expanded storage of calibration curves and data can be exported using USB output. The measurement range has increased to 0-9.9999 wt% to cover high sulfur crudes and shale oil markets.

  • Simple operation
  • Easy maintenance
  • Lightweight
  • Compact
  • Robust construction
Segment: Scientific
Division: SLFA
Manufacturing Company: HORIBA, Ltd.
  •  Measurement Procedure:

     • Pour the sample into the sample cell.
     • Place the sample cell on the sample holder
     • Set to the measurement condition
     • Press the "MEAS" button to start the measurement
     • Instrument displays the results and data output

  • Calibration
    New software features allow up to 15 separate calibration curves. There are three sets and each set represents 5 separate calibration curves. The software also allows the users to choose between linear or quadratic curves. Calibration curves are restored manually without having to recalibrate as long as coefficients value/calibration data are on hand.

  • Original Sample Cell
    To ensure accuracy and reliability of the analysis, HORIBA has maintained its original sample cell. By using the sample jig tool provided, you can easily seal the sample so that it is leak free.

  • Expanded Measurement Range (0~9.9999wt%)
    This new model can measure a wider range of sulfur content. It has an expanded range to measure from 0-9.9999 wt% sulfur, due to the higher sulfur concentrations of crude and shale oil markets.

  • Large printouts
    Printouts show important information, including sample ID, X-ray spectrum, date and time, measurement average value, standard deviation and calibration curve graph.

  • Data output
    The printout is available in an 80 mm wide format for easy comprehension.

  • Safety mechanism
    The SLFA-60 has a protective membrane covering the cell window to prevent the detector and X-ray tube from accidental sample leakage. This protective membrane unit is simple to assemble and replace.

  • Large screen display for easy viewing
    The screen will display real-time data to check the measurement conditions.

  • USB memory
    Your measurements can be recorded three different ways; by printout, exported to a USB memory device, or exported to an external PC through a USB interface, making it possible track and analyze the information throughout the lifetime of the unit.

Sulfur monitoring in Marine Oil with the SLFA in a growing environmental protection context
Sulfur monitoring in Marine Oil with the SLFA in a growing environmental protection context
Monitoring of Sulfur in petroleum products is an important topic in the current environmental protection context. Indeed, during combustion, Sulfur will cause acid rains and particles emissions that induce environmental and health problems. If industries and vehicles emissions have been the main target of Sulfur emission control since few tens of year, the new target is the maritime navigation. In this domain, now, the level of Sulfur is regulated by the MARPOL (International convention) Annex VI. For this specific regulation, the technique and measuring range of our SLFA series is perfectly suitable to allow the fast and accurate determination of Sulfur in Marine oil. Our compact SLFA-60 can be used on board and the SLFA-6800, with its autosampler (eight positions), will enhance the productivity of the control laboratories.
