- Model NEX CG - Cartesian Geometry EDXRF Spectrometer

0
By advanced Cartesian Geometry EDXRF, the Rigaku NEX CG spectrometer provides rapid, trace elemental analysis across a diverse range of matrices. Non-destructively analyze for elements sodium (Na) through uranium (U) in solids, liquids, powders, and thin films.

As a multi-purpose, high-performance EDXRF spectrometer, the Rigaku NEX CG delivers routine elemental measurements in a wide variety of sample types — from homogeneous, low viscosity liquids to solids, metals, slurries, powders, and pastes. Unlike conventional EDXRF analyzers, the NEX CG uses a unique close-coupled Cartesian Geometry (CG) optical kernel that dramatically increases signal-to-noise. Monochromatic or polarized excitation from secondary targets vastly improves detection limits for elements in highly scattering matrices like water, hydrocarbons, and biological materials. The dramatic reduction in background noise and a simultaneous increase in element peaks result in a spectrometer capable of trace element analysis even in the most challenging sample types. 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 NEX CG add to its broad appeal for applications ranging from research & development to industrial and in-plant quality assurance.

UltraCarry

Along with the ability to measure relatively large samples, a number of important options are available, including a vacuum system and sample spinner. With the patented Rigaku UltraCarry®, you can use the Rigaku NEX CG to quantify trace elements in aqueous liquids down to parts-per-billion (ppb) concentration levels. Replace ICP and AA wet chemistry methods with non-technical XRF trace elemental analysis.

Simple 3-step procedure
Unlike with ICP or AA instrumentation, anyone can quickly learn to use UltraCarry to perform routine trace element analysis. No acids, no plumbing, no filtering, no gases, no digestion and nothing to clean.

  1. Pipette your samples onto UltraCarry (A and B)
  2. Dry multiple samples simultaneously with Rigaku UltraDry™ vacuum hotplate with special metal disks for rapid drying (C)
  3. Analyze with Rigaku spectrometer (D and E)

For routine analysis, the Rigaku UltraDry vacuum hotplate (C) is recommended for rapid desiccation.
