MESA-50

X-Ray Fluorescence Analyzer

HORIBA has been selling the XGT-WR series of EDXRF analyzers for many years, providing screening measurements of samples containing hazardous elements such as Pb, Cd, Hg, Cr, Br, Sb, As for RoHS, ELV, and Cl for halogen free applications.

XGT systems are used daily throughout the world. HORIBA has now developed the new MESA-50 EDXRF analyzer, based on its long experience with customer requirements and knowledge. MESA-50 provides user friendly operation and good performance. MESA-50 includes three analysis diameters, suitable for every sample, from thin cables and electronic parts to bulk samples. The combination of SDD detector and Digital pulse processor(DPP) changes the image of EDXRF.

HORIBA's new MESA-50 supports ecological procurement; it contributes not only to EU RoHS and ELV compliance testing, but also regulatory work for many other countries.

We introduce a fast and non-destructive method for Pt catalyst loading mass determination in catalyst sheet of proton exchange membrane fuel cell using a benchtop EDXRF analyzer. We made a calibration curve by analyzing multiple in-house samples with different Pt loading masses (0.052 - 0.39 mg/cm2) and determined catalyst loading mass of a sample using the curve. Our result showed that the curve had a good linearity and that the calculated result was consistent with the labeled value of the sample with good repeatability.

Non-destructive Thickness and Composition Analysis of Coatings on Steel Using MESA-50

Steel coating plays an important role in preventing corrosion of steel samples. Therefore, an understanding of coatings can help in improving the steel properties. XRF is a powerful technique for measuring thickness and composition of coatings. We carried out non-destructive thickness and composition analysis of Zinc-Nickel coating on steel using the MESA-50 X-ray fluorescence analyzer.

Fast, easy and safe control of Zn-Ni galvanization baths with MESA-50, a portable EDXRF

The EDXRF technique is used for the elemental analysis not only of solids, but also of liquids such as plating solution thanks to dedicated sample cells. This specific example shows the ability of MESA-50 for electrolytic baths follow-up by characterizing the degradation of Zn-Ni galvanization baths.

Micro-XRF analysis for lead contamination in toys

A plastic toy is analysed for the presence of lead within its many components. Spot analysis shows concentrations of this harmful element can reach as high as 0.3%. XRF imaging allows its distribution across the toy to be quickly characterised.
