X-ray fluorescence (XRF) provides one of the simplest, most accurate and most economic analytical methods for the determination of elemental composition of many types of materials. Indispensable to both R&D and quality assurance (QA) functions, our advanced and unique WDXRF products are routinely used to analyze products from cement to plastics and from metals to food to semiconductor wafers. Rigaku offerings range from high power, high-performance wavelength dispersive WDXRF systems, for the most demanding applications, to a complete line of benchtop EDXRF and WDXRF systems. Rigaku also offers a, laser-induced breakdown spectroscopy (LIBS) handheld product, the Katana. LIBS is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites samples that then emit characteristic spectra for the elements in the sample.
