In studying the planetary processes and makeup of the
Earth (geology), geologists routinely analyze the composition of rock
and mineral samples. Rapid elemental analyses for sodium (
11Na)
through uranium (
92U) can be accomplished, through the use of
cost-effective, high-performance Energy Dispersive X-ray Fluorescence (EDXRF, XRF)
instrumentation without destruction, digestion or alteration of the
sample. Eliminating the need for a wet chemistry lab has made the EDXRF
technique of particular interest to the geological community.
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 Rigaku NEX CG EDXRF spectrometer
can significantly lower costs and reduce workload requirements for
routine elemental analysis needs.
Low cost analysis of geological materials
As a premium low cost benchtop Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer, the Rigaku NEX QC delivers wide elemental coverage with an easy-to-learn software interface in a robust package designed for industrial at-line quality control elemental analysis applications. The new Rigaku NEX QC features an intuitive "icon-driven" touch screen interface for easy operation and a built-in printer for convenience. The shuttered 50kV X-ray tube and Peltier cooled semiconductor detector deliver exceptional short-term repeatability and long-term reproducibility with excellent element peak resolution. This high voltage capability (50 kV), along with multiple automated X-ray tube filters, provides a wide range of applications versatility and low limits-of-detection (LOD). Options include fundamental parameters, automatic sample changer, sample spinner and helium purge for enhanced light element sensitivity.
