Wavelength-dispersive x-ray fluorescence spectrometer (Rigaku Supermini 200)

The Rigaku Supermini 200 (WD-XRF) is a wavelength-dispersive x-ray fluorescence spectrometer capable of analyzing the Flourine – Uranium elemental range using a Palladium (Pd) X-ray source running at 50KV and 4mA (200 W). The energy resolution of 20-30 eV provides superior sensitivity and spectral resolution allowing for more accurate deconvolution and elemental quantification especially when compared to energy-dispersive x-ray fluorescence systems. This energy resolution is achieved using 3 analyzer crystals: LiF (200) for the Ti-U range, PET crystal for Al-Ti, and RX-26 multilayer crystal for F, Na, and Mg. Capable of running solids, liquids, and gases with a maximum sample size of 44m diameter and 33mm height. Automated measurements are facilitated by an easy to use bidirectional 12-position automatic sample changer with integrated sample spinner to improve sampling statistics.
