Description

The wavelength dispersive X-Ray fluorescence spectrometer S8 Tiger 4 KW (Bruker) enables the detection of major and trace elements in one run. The chemical composition of rocks, minerals, ore and soil samples, and building materials can be measured in the form of powder tablets and glass beads at the lower ppm-level. Our element spectrum ranges from elements with mass 9 (F) to 92 (U).

Instruments

X-Ray Fluorescence spectrometer (XRF: Primary X-Rays are used to excite (fluoresce) X-rays in the specimen. A fused disc or pressed pellet is used for the determination of major element concentrations or trace element abundances in a bulk specimen. The X-ray detector utilizes a set of diffracting crystals specially positioned to detect one characteristic X-ray at-a-time. This sequential measurement of X-rays is termed Wavelength Dispersive Spectroscopy (WDS).
