X-ray Analysis Show Why van Gogh Paintings Lose their Shine
Scientists have identified a complex chemical reaction responsible for the degradation of two paintings by Vincent van Gogh and other artists of the late 19th century. This discovery is a first step towards understanding how to stop the bright yellow colours of van Gogh's most famous paintings from becoming covered by a brown shade, and fading over time. In the meantime, the results suggest shielding affected paintings as much as possible from UV and sunlight. more
XRF Analysis
Analysing minerals, ceramics and similar samples by XRF, the Vulcan fusion system, distributed in the UK by Analysco, uses automatic fusion control to achieve better sample uniformity and repeatability.more
HRSEM Study of Sn-Zn-Cu Film Formation
The formation of CuInSe2 and Cu2ZnSnSe4 thin films in the process of selenization precursor films was studied in use of combined microscopic (HRSEM) and spectroscopic (micro-XRF, EDS, micro-Raman and XRD) methods. more
Advances in µ - XRF
The macroscopic properties of technical materials are often determined by their elemental composition. Because most technical materials are inhomogeneous analytical methods are required that allow elemental analysis of these inhomogeneities - not only as a point by point measurement but also as a complete 2D-distribution. Micro X-ray fluorescence (µ XRF) has recently been established for this purpose. more
SEM/EDX-Analysis in Art History
Material analysis in art historical research provides information on dating, tracing the process of origin and state of preservation of art objects. Usually XRF and optical spectroscopy are used to study pigments in paintings. However these methods suffer from poor spatial resolution and therefore can not be used for the analysis of the layer structure of paintings. In these cases high resolution methods like SEM/EDX are indispensable. more
Just a Few Seconds
With the X-ray Guide Tube the bench top XGT-5000 systems allow convenient access to X-ray fluorescence analysis with high spatial resolution - from 1.2 mm down to 10 µm (HORIBA original). more
High-Resolution with X-Ray
Horiba Jobin Yvon presents two systems for high resolution microscopy. The XGT-7000 represents a completely new generation of XRF microscope. It offers a seamless merger between optical observation and elemental analysis functions. Unique hardware features ensure the system offers versatility and flexibility for every measurement. A choice of two software controlled x-ray guide tubes with diameters ranging from a unique 10 µm through to 1.2 mm allow conditions to be optimised for a range of measurements, including both micro and macro. more
Another Generation of Micro X-Ray Fluorescence Spectrometer
EDAX has introduced the Orbis micro-XRF elemental analyzer system, setting a new standard in analytical flexibility. Building on more than 10 years of micro-XRF experience, the Orbis spectrometer incorporates a motorized turret that integrates video and X-ray optics allowing coaxial sample view and X-ray analysis.Two additional X-ray collimators can be added to the optical turret for a total of three X-ray beam sizes to expand Orbis' analytical capabilities beyond traditional micro-XRF analysis. more
