Principle and Features of X-ray Fluorescence Spectrometry
Principle of Fluorescent X-ray Generation
When a sample is irradiated with X-rays from an X-ray tube, the atoms in the sample generate unique X-rays that are emitted from the sample. Such X-rays are known as "fluorescent X-rays" and they have a unique wavelength and energy that is characteristic of each element that generates them. Consequently, qualitative analysis can be performed by investigating the wavelengths of the X-rays. As the fluorescent X-ray intensity is a function of the concentration, quantitative analysis is also possible by measuring the amount of X-rays at the wavelength specific to each element.

Large Sample Chamber with Small Footprint
Installed width is 20% smaller than the previous instrument due to its compact body size.
The EDX-7000/8000 can accommodate samples up to a maximum size of W300 x D275 x approx. H100 mm.
High-Visibility LED Lamp
When X-rays are generated, an X-ray indicator at the rear of the instrument and an X-RAYS ON lamp at the front turn on, so that the instrument status can be monitored even from a distance.
PCEDX Navi Software Allows Easy Operation from the Start
PCEDX Navi software is designed to simplify X-ray fluorescence spectrometry for beginners, while providing the feature set and capabilities demanded by more experienced users.
The straightforward user interface offers intuitive operation and provides a convenient operating environment for beginners and experts alike.
Simple Screen Layout
Sample image display, analysis conditions selection, and sample name input on the same screen.
Collimator Switching from the Measurement Screen
Change the collimator diameter while observing the sample image. The selected diameter is indicated by a yellow circle.
Automatic Storage of Sample Images
The sample image is loaded automatically when the measurement starts. Sample images are saved with a link to the data file.
Once the measurement is complete, the element names, concentrations, 3σ (measurement variance) are displayed, together with the sample image, in an easy-to-understand layout.
Display the result list and individual report with a single mouse click.
Measurement Setup Screen Using the Turret (sample positioning screen)
Support for Continuous Measurements
PCEDX Navi supports measurements using the optional turret.
Switch between the sample image screen and sample positioning screen.
