We carried out non-destructive thickness and composition analysis of Zinc-Nickel coating on steel using the MESA-50 X-ray fluorescence analyzer.
Non-destructive Failure Analysis on Electronic Components Using the XGT-9000
μ-XRF is a non-destructive analytical technique which can inspect defects, even non-visible ones, inside a sample because of the high penetration of X-rays. This application note introduces failure analysis to detect ion migration, voids, and foreign matter on electronics using the XGT-9000, with key features of the vertical irradiation of a 10 μm probe and the simultaneous imaging of fluorescent X-rays and transmission X-rays.
Non-destructive large area elemental map imaging on the painting “Flower Vase with Thistles” using the XGT-9000SL
Pigments are important clues to the historical background of artworks. This application note introduces elemental map imaging performed on Vincent van Gogh’s oil painting “Flower Vase with Thistles” using the XGT-9000SL. The results reveal that elemental compositions of the pigments used on the painting were different from ones previously reported to have been used by van Gogh. It suggests that this painting was a replica of the artwork.
Fast, easy and safe control of Zn-Ni galvanization baths with MESA-50, a portable EDXRF
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.

Characterization of Pyrite Inclusions in Lapis Lazuli Using X-ray Fluorescence Micro-imaging
Lapis lazuli is a deep-blue metamorphic rock used as a semiprecious stone which contains inclusions that can impact its value. Pyrite impurities and major elements distribution are studied with the XGT-9000, HORIBA’s new X-ray microscope.
Pigment identification of an old Japanese flag “Hinomaru” using micro-XRF and Raman microscopy
This application note introduces pigment identification using micro-XRF and Raman microscopy on a Japanese flag “Hinomaru”, which is presumed to be the oldest and designed by an ancient Japanese Emperor Go-Daigo. The two spectroscopic analyses identified that the red pigment used on the flag matched the cinnabar ore (Mercury(II) sulfide) mined from the Mine near the place where the Emperor lived.
Spectroscopic Analysis Explains the Mystery of Dragonfly Eye Beads
Spectroscopic analysis can reveal the origin of cultural heritages and the historical background at the time. This application note introduces research of a dragonfly eye bead found in a tomb in China. Using Raman spectroscopy and X-ray analytical microscopy, the bead was found to be from the Eastern Mediterranean region and the result suggested China had cultural and economic exchanges with them during that era.
