Product information

Unlike other techniques available (e.g. titration), X-ray fluorescence (XRF) is rapid, simple, and does not require the use of chemicals. It is a field-proven technique that is widely used in the oil industry. With results available in seconds, it is a nondestructive technique, and can be used by any operator with minimal training.

Our field-portable XRF analyser, the X-MET8000, combines a high performance X-ray tube and large area silicon drift detector (SDD) to deliver the speed and performance needed for the routine determination of sulfur in fuels.

Robust (IP54 rated to ensure minimal ingress of dust and splash water; tested to MIL-STD 810G for ruggedness) and compact, the X-MET is versatile and can be used on-board a ship, in a laboratory, or taken to where the analysis needs to be performed.

The X-MET offers users flexible data management to suit all needs: results are automatically stored in the analyser. They can be transferred to a USB flash drive or a PC, printed on a portable Bluetooth printer, or shared in real-time through our App and cloud service.

Sample Preparation

The sample preparation is simple: just pour the solution into a sample cup fitted with thin polyester film (e.g. 3.5μm Mylar(r)), and place it in the safety window, also fitted with thin film. This minimises the risk for spill, cross contamination or cup leakage onto the analyser, and avoids costly repairs.

The cup and safety window are placed in the light stand or the benchtop stand for analysis. Pressing the X-MET trigger starts the analysis, and initial results are available in seconds, updating until the end of the analysis.

A typical analysis time for marine fuel oil is 60 seconds.
