X-ray fluorescence (XRF)
Composition identification, Elemental analysis, Qualitative analysis,Quantitative analysis
As a tube-above sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer, the new Rigaku ZSX Primus IV delivers rapid quantitative determination of major and minor atomic elements, from beryllium (Be) through uranium (U), in a wide variety of sample types — with minimal standards.
New ZSX Guidance expert system XRF software
ZSX Guidance supports you in all aspects of XRF measurement and data analysis. Can accurate analysis only be performed by experts ? No — that is in the past. ZSX Guidance software, with the built-in XRF expertise and know-how of skilled experts, takes care of sophisticated settings. Operators simply input basic information about samples, analysis components and standard composition. Measured lines with the least overlap, optimum backgrounds and correction parameters (including line overlaps) are automatically set with aid of qualitative spectra.
Exceptional light element XRF performance with inverted optics for superior reliability
ZSX Primus IV features an innovative optics-above configuration. Never again worry about a contaminated beam path or down time due to sample chamber maintenance. The optics-above geometry eliminates cleaning worries and increases up time. Providing superior performance with the flexibility for analyzing the most complex samples, the ZSX Primus IV WDXRF spectrometer features a 30 micron tube, the thinnest end-window tube available in the industry, for exceptional light element (low-Z) detection limits.

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical elementsuch as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride.In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero.[1]Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals can become nonmetals. Sodium, for example, becomes a nonmetal at pressure of just under two million times atmospheric pressure.In chemistry, two elements that would otherwise qualify (in physics) as brittle metals—arsenic and antimony—are commonly instead recognised as metalloids, on account of their predominately non-metallic chemistry. Around 95 of the 118 elements in the periodic table are metals (or are likely to be such). The number is inexact as the boundaries between metals, nonmetals, and metalloids fluctuate slightly due to a lack of universally accepted definitions of the categories involved.In astrophysics the term "metal" is cast more widely to refer to all chemical elements in a star that are heavier than the lightest two, hydrogen and helium, and not just traditional metals. A star fuses lighter atoms, mostly hydrogen and helium, into heavier atoms over its lifetime. Used in that sense, the metallicityof an astronomical object is the proportion of its matter made up of the heavier chemical elements.Metals, as chemical elements, comprise 25% of the Earth's crust and are present in many aspects of modern life. The strength and resilience of some metals has led to their frequent use in, for example, high-rise building and bridge construction, as well as most vehicles, many home appliances, tools, pipes, and railroad tracks. Precious metals were historically used as coinage, but in the modern era, coinage metals have extended to at least 23 of the chemical elements.The history of metals is thought to begin with the use of copper about 11,000 years ago. Gold, silver, iron (as meteoric iron), lead, and brass were likewise in use before the first known appearance of bronze in the 5th millennium BCE. Subsequent developments include the production of early forms of steel; the discovery of sodium—the first light metal—in 1809; the rise of modern alloy steels; and, since the end of World War II, the development of more sophisticated alloys.
