Corrections for a mix of light elements

The matrix of a liquid can contain compounds that cannot be not measured by XRF (e.g. -CH2-, -CHOOCH2- or -CH2OCH2-). The matrix effects of these compounds, however, are very different and influence the accuracy.

For an accurate analysis of elements like sulfur the determination of these compounds is crucial. These compounds have a high influence on the Compton scattered tube intensity. For this reason the FP model is extended with a model to calculate the theoretical intensity of scattered tube intensity.

Oil-Trace exploits this advanced FP model to correct for the influence of these compounds, resulting in increased accuracy for elements like Mg, Al, Si, S and P.

Correcting errors due to sample variations

In XRF, the irradiated volume of the sample that is analyzed depends on the density of the sample and the energy (penetrating power) of the analyte element X-rays. For most solid samples this can be ignored. However, for low-density liquid samples it becomes an important factor contributing to the accuracy of analysis, particularly for heavier elements.

Oil-Trace corrects for the varying volume of the fluorescence volume geometry (FVG).

Compliancy with international norms

Oil-Trace supports compliancy with international ASTM and ISO norms and methods. It is particularly useful for the analysis of fuels, biofuels and mixtures, e.g. B20, E5, E85, additives in lubricating oils and wear metals in used oils, S, Ni, V and other restricted elements in crude oils and further refined oils, chlorine in compressor oils, metals in homogeneous liquid catalysts and troubleshooting for catalyst poisoning

Unique setup samples

Oil-Trace is a package consisting of a suite of standards and specialized software. These standards are used to set up a base line calibration based on PANalyticals 5th generation FP model and reduce the need for many different reference materials.
