Multiple Characterizations of a Blister Pack Using the XGT-9000
Multiple Characterizations of a Blister Pack Using the XGT-9000
The XGT-9000 is HORIBA’s new X-ray microscope. Its analytical versatility allows, multiple characterizations to be performed on a blister pack, from mapping of the full pack to particle size measurements of the capsule content.
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.
Optical Micro-spectroscopies on a Path to Identify the Source of Life
Optical Micro-spectroscopies on a Path to Identify the Source of Life
In this article, we present how our Raman and X-Ray Fluorescence microscopies can be combined to shed some light on the origins of the universe. We show some examples on a meteorite piece and on water inclusion in quartz matrix.
Fast thickness measurement of thin metal coatings by Micro-XRF
The penetrating nature of EDXRF analysis allows multi-layered samples to be characterised with a single measurement. With high spatial resolution even microscopic features such as bonding pads on circuit boards can be interrogated for composition and layer thickness.
Particle Analysis of Film and Battery
The XGT-9000 can detect and determine the composition of foreign particles, and therefore track the source of contamination.
QC, Counterfeit Products, Presence of Foreign Materials
X-ray Fluorescence photons can be partially absorbed by the encapsulated material and will not show in the spectrum. The X-ray transmission image provides a complete picture.
QC of Semiconductors which Feature Thin and Narrow Patterns
Semiconductor pattern - XGT-9000
The combination of microbeam and thickness measurement capability makes the XGT-9000 a useful tool for the QC of semiconductors, which feature thin and narrow patterns. Thickness sensitivity depends on elements traced, but can be at the Angstrom level.
Characterization of Pyrite Inclusions in Lapis Lazuli Using X-ray Fluorescence Micro-imaging
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.
Quality control and defect analysis in the electronics industry using micro-XRF
Troubleshooting and defect analyses of components embedded within opaque resins are described, on both individual components and complete circuit boards. Quantitative analysis to the ppm level is ideally suited for ensuring compliance to the WEEE/RoHS directives.
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.
Micro-XRF for non destructive analysis of museum and archaeological objects
Micro-XRF for non destructive analysis of museum and archaeological objects
Pigments used in an ancient Nepalese manuscript have been analysed and assigned and an ancient glass burial ornament has been probed to identify the specific colouring additives used.
Elemental micro-analysis of leaves using EDXRF
Calcium micro-nodules are identified within mulberry leaves, and XRF mapped imaging provides a correlation between nodule concentration and leaf age. In a seperate study, the uptake of heavy element pollutants by plants is investigated, with high resolution images quickly acquired to show the distribution of lead through the leaf.
Micro-XRF analysis for the Electronics Industry
The combination of the XGT-5000’s ground breaking spatial resolution and sensitivity means it is the instrument of choice for fast analysis of electronic components, whether for analysis of restricted harmful elements (the WEEE/RoHS ‘lead free’ legislation), trouble shooting, or R&D.
Biological applications of XRF microscopy
The effect of zinc on gastric ulcer healing has been investigated - mapped imaging of tissue samples shows evidence of zinc accumulation within the ulcerated tissue. In a separate study a fish otolith ('ear bone') has been analysed to reveal its heterogeneous elemental composition and physical structure.
Micro-XRF analysis for metal debris and particle analysis
Fast analysis of microscopic metal particles is an important application for engineering (e.g. engine wear analysis). Micro-XRF scanning and spot analysis of specific fragments identifies their chemical composition.
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.
The non-destructive identification of black ink in a tempered document using XGT-9000
μ-XRF is one of the powerful non-destructive analytical technique in forensic science application. Thanks to the elemental mapping and the spectrum search function, XGT-9000 enables to reveal intentional alternation and identify the ink used on a document.

Elemental analysis of single rice grains using XRF micro-analysis
Individual rice grains are analyzed by micro-XRF to examine the effect of grain polishing. The concentration of mineral elemnts found on a grain can be related to the degree of polish.
Gun Shot Residue analysis using X-ray fluorescence micro-analysis
Micro-XRF analysis of gun shot residues allows individual microscopic particles to be characterized for elemental composition. In addition, automated element imaging provides high spatial resolution element distribution maps, allowing particle shapes and sizes to be accurately analyzed.
