XRF
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
Atomic
Absorption laboratory (burning Li solution).
Descrition
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.
