Alkaline earth oxide or carbonate containing particle analysis using multi-energy x-ray detection

A method for monitoring at least one physico-chemical parameter of quicklime particle(s), the method comprising:

• a) irradiating the particle(s) with at least one X-Ray source;
• b) collecting radiation passing through the particle(s) in an X-ray detector, the detector comprising at least one detection area, in particular pixel areas, the area being adapted to detect multiple energy bins, wherein each energy bin comprises a range of energy levels;
• c) measuring intensities or fluxes of the collected radiation for each energy bin and for each detection area;
• d) determining at least one value from the measured intensities or fluxes for each energy bin and for each detection area;
• e) determining the at least one physico-chemical parameter of the particle(s) as a function of the at least one value obtained for each energy bin and for each detection area;
• f) recording photon counts arriving at the at least one detection area and sorting each count into the multiple energy bins of each detection area.
