Rigaku NEX CG delivers rapid qualitative and quantitative
determination of major and minor atomic elements in a wide variety of
sample types — with minimal standards.
Cartesian geometry for trace level sensitivity
Unlike conventional EDXRF analyzers, the NEX CG was engineered with a
unique close-coupled Cartesian Geometry (CG) optical kernel that
dramatically increases signal-to-noise. Monochromatic or polarized
excitation from secondary targets, instead of conventional “noisy” white
radiation (Bremsstrahlung) direct excitation, vastly improves detection
limits for elements in highly scattering matrices like water,
hydrocarbons, and biological materials. The resulting dramatic reduction
in background noise, and simultaneous increase in element peaks,
affords a spectrometer capable of routine trace element analysis even in
difficult sample types. Up to five secondary targets cover the complete
elemental range (Na – U) with optimized sensitivity. Excitation is
provided by a close-coupled 50 watt Pd-anode end-window X-ray tube. For
maximum stability, the tube is fitted with a shutter so that the tube
may remain on at all times for maximum stability and durability. An
available uninterruptable power supply (UPS) compensates for power line
fluctuations and extends tube life. Superior counting statistics and
designed-in high stability translate into extraordinary analytical
performance.
Highest sensitivity for broad flexibility
As a multi-purpose, high-performance EDXRF spectrometer, the Rigaku
NEX CG delivers routine elemental measurements across a diverse range of
matrices — from homogeneous, low viscosity liquids to solids, metals,
slurries, powders, pastes and thin films. Especially well-suited to the
semi-quantitative determination of elemental content in complete
unknowns, the superior analytical power, flexibility and ease-of-use of
the Rigaku NEX CG add to its broad appeal for applications ranging from
research & development to industrial and in-plant quality assurance.
Novel software reduces the need for standards
NEX CG 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 standards. Rigaku NEX CG software was developed to be both
extraordinarily powerful and extremely easy to use. Ideal for
non-technical operators, routine analyses are performed through a
simplified customizable EZ Analysis interface. Software operation simply
involves selecting the sample position on the computer screen and
entering a sample name. Next, the application method (i.e., calibration)
is selected. Selecting the “start” button with the mouse pointer
initiates the analysis. The depth and breadth of features, as well as
the sophistication of the interface, is the result of decades of XRF
software development at Rigaku.
