Rigaku Corporation located in Austin, Texas USA is a new research and development, manufacturing, sales, service and support subsidiary of Rigaku Americas Corporation dedicated to energy dispersive X-ray fluorescence (EDXRF) and related elemental analysis technologies.

Rigaku Corporation’s product portfolio includes benchtop EDXRF elemental spectrometers in addition to process control instrumentation for real time closed loop control.

This new U.S.-based "EDXRF Center of Excellence" is located in an all new 20,000 square foot facility in the northwest quadrant of Austin, Texas. As an affiliated company of the Rigaku XRF product group based in Osaka, Japan, Rigaku Corporation will participate in the co-development of novel and cost-effective X-ray based analytical instruments and techniques to better serve the metrology requirements of the company's expanding global customer base. The objective of this innovative organization structure is to provide industry, academia and governments with worldwide access to the latest in X-ray analytical technologies, while delivering a partnership-level service and support experience to customers.

Energy Dispersive X-Ray Fluorescence (EDXRF)
Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopy provides one of the simplest, most accurate and most economic elemental analytical methods for the determination of the chemical and/or elemental composition of many types of materials. The technique is generally non-destructive, requiring little if any sample preparation, and is suitable for almost all sample types.

Fundamental Parameters (FP) Software
Rigaku X-ray spectrometers may be used in conjunction with Fundamental Parameters (FP) software to allow for elemental quantification of completely unknown samples without standards. For example, the Rigaku NEX CG energy dispersive X-ray fluorescence analyzer is powered by new qualitative and quantitative analytical software, RPF-SQX that features Rigaku Profile Fitting (RPF) technology. The software allows semi-quantitative elemental analysis of almost all sample types without standards – and rigorous quantitative analysis with standards. Featuring Rigaku’s famous Scatter FP method, the software can automatically estimate the elemental concentration of unobserved low atomic number elements (H to F) and provide appropriate corrections.

X-Ray Transmission (XRT) Sulfur Process Gauge
X-ray Transmission (XRT) gauging has long been an accepted technique for the measurement of sulfur (S) in heavy hydrocarbon process streams. Whether used for pipeline switching, crude oil blending or to assay or blend marine and bunker fuels, the Rigaku NEX XT XRT process analyzer is well suited to rigorous process environments, with pressures up to 1480 psig and temperature up to 200°C.

EDXRF Elemental Analysis Applications
Typical uses of EDXRF include the analysis of petroleum oils and fuel, plastic, rubber and textiles, pharmaceutical products, foodstuffs, cosmetics and body care products, fertilizers, geological materials, mining feeds, slags and tails, cement, heat-resistant materials, glass, ceramics, catalysts, wafers; the determination of coatings on paper, film, polyester; metals and alloys, glass and plastic; forensics; multi-layer thin films on silicon wafers, photovoltaics and rotating storage media as well as pollution monitoring of solid waste, effluent, cleaning fluids, pools and filters. In addition, X-ray Transmission (XRT) process gauges are employed to measure sulfur (S) in crude oil and marine bunker fuel.
