Rigaku NEX QC EDXRF

Applied Rigaku Technologies, Inc. today announced a new method for the petroleum market which demonstrates the capabilities of the advanced low-cost Rigaku NEX QC EDXRF benchtop analyzer. The new method, presented in Rigaku Application Note #1249, describes the measurement of Phosphorus (P) Sulfur (S) Calcium (Ca) and Zinc (Z) in lube oil in compliance with ASTM D6481-99 and demonstrates the effectiveness of the NEX QC benchtop EDXRF analyzer for the elemental analysis of lube oil by Energy Dispersive X-ray Fluorescence spectrometry.

Certain oils are formulated with organo-metallic additives which act as detergents, antioxidants, and anti-wear agents. These additives often contain one or more of the noted elements. Determining the concentrations of these elements therefore provides an indication of the additive content of the oils.

Quality control and quality assurance during the lube oil manufacturing process is essential and a quick, easy method for analyzing lube oils is needed throughout the QC/QA process. The test method described covers the quantitative determination of additive elements in unused lubricating oils and is primarily designed to be used at the manufacturing location for the monitoring of additive elements, but is also suitable for use in central and research laboratories.

For this method, empirical calibrations were built using a suite of 16 commercially available calibration standards which are representative of the lube oil formulation being analyzed. The results demonstrate excellent performance for analyzing basic lube oil formulations using the NEX QC analyzer. Optimized for quality control applications, the NEX QC features a 50kV X-ray tube for wide elemental coverage, a modern icon driven user interface, USB and Ethernet connections for data logging and storage, and optional Fundamental Parameters software enabling elemental quantification of unknown samples without standards. Fast and simple, the NEX QC analyzer is shown to be an ideal tool for monitoring and controlling lube oil additives and formulations during blending and process QC.
