Catalysts

Elemental analysis for composition, stoichiometry and poisoning agents

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), 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 technology and know-how provide a number of unique solutions for these determinations.

Semiquantitative elemental analysis without standards

The 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.
