EDXRF / XRF for Portland Cement and Cementitious Materials

Unsurpassed Light Element Sensitivity and Analytical Performance

Modern Portland cement is made by mixing lime, silica, alumina, and iron oxide substances and then heating the mixture until it almost fuses. During the heating process, dicalcium and tricalcium silicate, tricalcium aluminate, and a solid solution containing iron are formed. X-ray fluorescence (XRF), a standard technique used across the cement industry, determines metal-oxide concentrations and oxide stoichiometry. The Rigaku NEX CG II advanced energy dispersive X-ray fluorescence (EDXRF) spectrometer, with its high sensitivity for light (low atomic number) elements, is the perfect cost-effective backup or supplement to your WDXRF system.

EDXRF for Changing Feeds

NEX CG II is powered by Rigaku's RPF-SQX Fundamental Parameters, an advanced qualitative and quantitative analytical software featuring Rigaku Profile Fitting (RPF) technology and Scattering FP. The software allows semi-quantitative analysis of almost all sample types without standards – and rigorous quantitative analysis with standards. Rigaku's Scattering FP method automatically estimates the concentration of unmeasurable low atomic number elements (hydrogen to fluorine) and provides appropriate corrections.

Affordable Cement Analyzer

During the entire production and processing cycle, the oxide composition of the cement material must be reliably monitored to ensure optimal process control, physical characteristics of the cement, and profitability. The Rigaku NEX QC gives the cement plant a reliable and affordable system for QC measurements around the plant, making it an ideal tool throughout the quality control process and as a backup to WDXRF systems. The NEX QC is applicable to clinker and raw meal materials and can be used to measure gypsum (SO3) in finished cement.
