PANalytical Zetium WD-XRF

Description

Zetium is a wavelength-dispersive X-ray fluorescence (WD-XRF) spectrometer for quantitative elemental analysis from 0.05 to 100wt%. This instrument uses an X-ray source to eject core-shell electrons from an atom to create an excited state. The resulting cascade of electrons to fill the holes results in emission of X-radiation from the atom (fluorescence) that has a characteristic wavelength/energy specific to each element. Zetium uses several Bragg gratings to resolve the X-ray light by wavelength.

Typical analysis requires either destructive preparation of ~1g inorganic solid to produce a lithium borate glass bead to quantify X-ray fluorescence for each element at percent levels (major analysis); or preparation of 10 g inorganic solid to produce a pressed pellet to quantify elements from tens of ppm levels (trace analysis).
