XRF
RIX 2100 sequential X-Ray spectrometer 4 KW X-ray tube, 10 position crystal changer
Description:
The Rigaku RIX 2100 wavelength-dispersive x-ray fluorescence unit (XRF) is used chiefly for quantitative major element (Si, Al, Fe, Na, K, Mg, Ca, Mn,
Ti, P) determinations in rocks, minerals, ceramics, nanocompounds, cements, clays, alloys, etc. The major trace elements which can be determined by XRF
(on a pressed powder) are Rb, Sr, Y, Zr, Nb, Zn, Co, Cu, Ni, Ba, and Cr. Qualitative or semi-quantitative scans can be run on elements carbon through
uranium. Solid samples containing Li or Be must be dissolved by fusion or acid dissolution and determined by flame atomic absorption (FAA) due to
insensitivity by XRF.

Atomic Absorption Lab
Description:
The flame atomic absorption (FAA) is used chiefly for cations in water, wastewater, environmental samples, etc. Elements from Be to rare earth elements
can be determined with varying degrees of sensitivity and accuracy. Traces of gold can be detemined by aqua regia digestion followed by solvent extraction.
Atomic Absorption laboratory (burning Li solution).
