Additives, substances added in or onto paper products to improve their performance, or to enhance their attractiveness or value, are critical to the paper making process. Energy Dispersive X-ray Fluorescence (EDXRF), a standard technique across the paper industry, is used to determine oxide concentrations, coating thickness & composition, and other important paper chemistries. Minimized standards with RPF-SQX analytical softwareThe Rigaku NEX CG EDXRF is powered by a new qualitative and quantitative analytical software, RPF-SQX, that features Rigaku Profile Fitting (RPF) technology. The software allows semi-quantitative analysis of almost all sample types without standards - and rigorous quantitative analysis with a few standards. Featuring Rigaku's famous Scatter FP method, the software can automatically estimate the concentration of unobserved low atomic number elements (H to F) and provide appropriate corrections. RPF-SQX greatly reduces the number of required standards, for a given level of calibration fit, as compared to conventional EDXRF analytical software. As standards are expensive, and can be difficult to obtain for newly developed materials, the utility of having a NEX CG spectrometer can significantly lower costs and reduce workload requirements for routine elemental analysis needs.
