EDXRF / XRF for Catalysts

Catalysts are substances that can cause a change in the rate of a chemical reaction without itself being consumed in the reaction; the changing of the reaction rate by use of a catalyst is called catalysis. Energy Dispersive X-ray Fluorescence (EDXRF, XRF), a commonly employed technique across industries - using either heterogeneous or homogeneous catalysts - to determine heavy metal concentrations or stoichiometry and/or to quantify poisoning agents. Rigaku's XRF technology and know-how provide a number of unique solutions for these determinations.

Semiquantitative elemental analysis without standards

The Rigaku NEX CG EDXRF (XRF) is powered by a new qualitative and quantitative analytical software, RPF-SQX, that features Rigaku Profile Fitting (RPF) technology. This XRF 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 XRF 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 (XRF) analytical software. As standards are expensive, and can be difficult to obtain for newly developed materials, the utility of having a Rigaku NEX CG EDXRF spectrometer can significantly lower costs and reduce workload requirements for routine elemental analysis needs.
