Description

The X-Ray Fluorescence (XRF) Lab houses a Bruker S8 Tiger X-Ray fluorescence sequence spectrometer that is used for quantitative analysis of the main and trace elements of bulk rock and mineral samples. Element contents as low as the parts per million (mg/g) range can be obtained by XRF from bulk samples that were previously either finely ground and pressed into a tablet or molten and subsequently cast into a glassy disk. The analyser can be used on-site as well as for sample-based research projects for analyses and also for the pre-selection of samples for highly specific geochemical investigations (INNA, REE and PGE analysis).

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).
