New D4294 Sulfur EDXRF also Measures Cl, V, Fe, and Ni
Oct 19 2011 Comments 0
To meet the needs of ASTM D4294 sulfur applications, Rigaku introduces the new low-cost NEX QC energy dispersive X-ray fluorescence (EDXRF) analyzer. Featuring D4294 compliance in air, with an autosampler and C/H correction, the instrument is also ideal for measuring heavy elements (like: V, Fe, Ni) and chlorine (Cl) in crude oil as well as other heavy and refined petroleum products.
Specifically designed for routine petroleum applications, the new Rigaku NEX QC features an intuitive “icon-driven” touch screen interface for easy operation and a built-in printer for convenience. The shuttered 50kV X-ray tube and Peltier cooled semiconductor detector deliver exceptional short-term repeatability and long-term reproducibility with excellent element peak resolution. This high voltage capability (50 kV), along with multiple automated X-ray tube filters, provides a wide range of applications versatility and low limits-of-detection (LOD). Applications for the NEX QC range across a broad spectrum of analytical needs, including: crude oil, marine and bunker fuels, diesel, heavies, lubricating oils and other petrochemicals.
About Applied Rigaku Technologies, Inc.
Applied Rigaku Technologies, Inc. (ART) 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.
This 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, ART participates 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, academe and governments — worldwide access to the latest in X-ray analytical technologies while delivering to customers a partnership-level service and support experience.
The company designs and manufacturers benchtop Energy Dispersive X-ray Fluorescence (EDXRF) elemental analysis instrumentation for non-destructive analytical chemistry applications, including atomic spectroscopy (spectrometry), quantitative and qualitative elemental analysis. Current instruments include the state-of-the-art polarized (Cartesian geometry) Rigaku NEX CG EDXRF spectrometer and the new lost-cost Rigaku NEX QC EDXRF elemental analyzer. In addition, ART offers a 3rd generation X-ray Transmission (X-ray Absorption) process gauge for the determination of sulfur (sulphur) in a wide variety of heavy viscous hydrocarbon matrices, including bunker fuels, crude oil, and residuums.
