SLFA-60

X-ray Fluorescence Sulfur-in-Oil Analyzer

Safer, Simpler and Swift: Effortless Sulfur Analysis in Oil

Ultra-low Detection Limit: It measures sulfur concentrations of 20 ppm or less, and can measure higher sulfur concentrations of crude and shale oil markets, up to 9.9999 wt%.
Portability at Its Best: Take it anywhere with ease - only 9 kg weight with small footprint.
Enhanced Safety: In addition to the thorough X-ray leakage test performed at the factory, the key switch and shield shutter provide additional protection for the operator.
Simple Operation: After selecting the calibration curves and measurement conditions, or selecting the correct calibration curve using the "A" mode, simply press the "MEAS" button to start the measurement.

Measurable Oils
Petroleum products such as heavy oil, naphtha, crude oil, shale oil and diesel oil.

Compliant with Standards

Where can it be installed?

The SLFA-60 is a compact sulfur-in-oil analyzer based on energy-dispersive X-ray fluorescence (EDXRF) technology. It is portable and can be used on-board, thanks to its pump-free and LN2-free optics. The SLFA-60 series does not require a laptop or external printer, making it flexible to install in any location.

How can I get data without operational computer and printer?

The SLFA-60 has an integrated large-screen display and touch buttons on the main unit, which makes it easier for users to operate the device intuitively. The buttons are covered with a resin sheet to prevent oil from adhering to the device and make it easier to keep it clean. The SLFA-60 also has an integrated printer that can print out all the necessary information on 80 mm wide paper.

How does it protect the device from oil leakage accident?

The SLFA-60 has a protective membrane under the sample cell. It protects the optics (detector and X-ray tube) from accidental sample leakage. The protective membrane is a single unit that is easy for the user to replace.

Is it safe from X-ray exposure?

The SLFA-60 has a two-tier safety system to prevent X-ray leakage: an X-ray shield, an interlock function, and a shutter function. The X-ray shield blocks X-rays from escaping the instrument. The interlock function prevents the X-ray tube from operating if the chamber lid is open. The shutter function closes over the X-ray port once the chamber lid is open, further preventing X-ray leakage. The SLFA-60 meets the requirements of IEC 61010-1, which specifies that the X-ray leakage rate must be under 5 µSv per hour. The SLFA-60 goes even further, with a design specification of under 1 µSv per hour. This means that the SLFA-60 is one of the safest X-ray fluorescence analyzers on the market.

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.
