AUSTIN, Texas, Sept. 3, 2009 – Applied Rigaku Technologies Inc. has introduced a benchtop energy dispersive x-ray fluorescence (EDXRF) spectrometer, the Rigaku NEX CG, which delivers rapid qualitative and quantitative determination of major and minor atomic elements in a wide variety of sample types with minimal standards and little, if any, sample preparation.
It can nondestructively analyze elements from sodium through uranium in solids, liquids, powders and thin films. Employing polarized excitation for lower detection limits and software for reduced standards' requirements, the instrument provides part-per-billion level detection limits for aqueous samples when used with the patented UltraCarry sample holder. A simplified user interface, EZ Analysis, enables routine operation by nontechnical personnel.
Unlike conventional EDXRF analyzers, it was engineered with a close-coupled Cartesian geometry (CG) optical kernel that dramatically increases the signal-to-noise ratio. Using secondary target excitation instead of conventional direct excitation further improves sensitivity. The resulting reduction in background noise and simultaneous increase in element peaks result in a spectrometer that can perform routine trace element analysis even in difficult sample types.
It is powered by new qualitative and quantitative analytical software, RPF-SQX, which features Rigaku profile fitting technology. The software allows semi-quantitative analysis of almost all sample types without standards, and rigorous quantitative analysis with standards. Especially well suited to semiquantitative determination of elemental content in complete unknowns, the good analytical power, flexibility and ease-of-use of the instrument add to its appeal for research, industrial and in-plant monitoring.
Applications include analysis of petroleum oils and fuel, plastic, rubber and textiles, pharmaceutical products, foodstuffs, cosmetics, fertilizers, geological materials, mining feeds, slags and tails, cement, heat-resistant materials, glass, ceramics, catalysts and wafers. It also can determine coatings on paper, film and polyester, metals, alloys, glass and plastic. It can be used in forensic applications and for monitoring solid waste, effluent, cleaning fluids, pools and filters.
