Austin, TX (PRWEB) January 27, 2012

Applied Rigaku Technologies, Inc. today announced a new empirical method for the elemental analysis of Mg, Al, Si, Ca and Fe in limestone. Application Note #1108 demonstrates the effectiveness of the polarized excitation and Cartesian geometry design of the Rigaku NEX GC energy dispersive X-ray fluorescence (EDXRF) spectrometer to provide superior light element sensitivity.

Calcium-bearing minerals are widely used in agriculture, energy, and road construction. Limestone has long been used as a key material in the construction of buildings and monuments, as well as the production of glass. It is used as a raw material in the production of quicklime, cement and mortar. Limestone is also used as a scrubber stone in the desulfurization of flue gas and as a reagent in blast furnaces to extract iron from ore. Purified, limestone has many uses as a calcium supplement in foods and animal feeds, and well as a whitener in cosmetics.

For this application, each sample is prepared by grinding to a fine, dry, homogeneous powder of
