XRF Spectrometers

X-ray fluorescence (XRF) is an analytical technique used for non-destructive elemental analysis of a wide range of materials. It relies on the principle that when a material is irradiated with high-energy X-rays, the atoms within the material are excited, leading to the emission of characteristic X-ray fluorescence radiation. By detecting and analyzing these emitted X-rays, the elemental composition of the sample can be determined.

Rigaku offers different X-ray fluorescence technologies. Each type of XRF spectrometer has its own strengths and limitations, and the choice of instrument depends on factors such as the sample type, required sensitivity, and analytical precision. XRF is widely used in various industries, including mining, petroleum, metallurgy, environmental science, and archaeology, for qualitative and quantitative elemental analysis of a wide range of materials.

WDXRF_ProductImages
Wavelength dispersive XRF

In WDXRF, a crystal or grating is used to disperse the X-rays emitted from the sample. WDXRF offers high spectral resolution and is particularly well-suited for analyzing elements with overlapping X-ray emission lines.

EDXRF_ProductImages
Energy dispersive XRF

In EDXRF, the emitted X-rays are directly detected by a detector. It is suitable for routine elemental analysis in various fields, including environmental monitoring, petroleum, mining, and materials science.

TXRF_ProductImages
Total reflection XRF

In TXRF, the sample is deposited onto a flat substrate, and an X-ray beam is directed onto the sample at a very shallow angle. The emitted fluorescence radiation is then detected and analyzed, providing highly sensitive elemental analysis with low detection limits.
