Rigaku EDXRF analyzers are capable of measuring more than just sulfur. From the quantification of heavy elements in crude oil to sulfur in fuels to a variety of elements in lubricating oils, EDXRF is a well-established technique for the petroleum and petrochemical industries. Rigaku EDXRF products show versatility for many screening needs and meet compliance with various testing methods and standards. With multi-element analysis capabilities, measure for your elements of interest in almost any matrix.
The Rigaku NEX QC benchtop EDXRF combines superior performance capabilities with affordability. This analyzer is ideal for measuring sulfur in oils by ASTM D4294 (also methods ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4), lead in gasoline by ASTM D5059, and the NEX QC+ model delivers compliance with the ISO 13032 sulfur method for ULSD (ultra-low sulfur diesel). These instruments are designed and engineered for heavy industrial use, whether plant floor or remote field environments and feature an intuitive icon-driven touchscreen interface for easy operation and a built-in thermal printer for convenience.
The NEX DE high-performance spectrometer delivers rapid elemental analysis — analyze sulfur, calcium, vanadium, iron, and nickel in crude, residual oil, bunker fuels, and other heavy hydrocarbon oils. NEX DE is ideal for quick ASTM D8252-19 compliance of nickel and vanadium or measuring chlorine by ASTM D4929 Part C.
The NEX CG II, an indirect excitation EDXRF analyzer, is capable of trace element analysis even in the most challenging sample types. NEX CG II is well suited to meet ASTM and international compliance for ultra-low sulfur applications, such as testing ultra-low sulfur in diesel and meeting Tier 3 gasoline requirements per ASTM D7220. NEX CG II delivers the lowest chlorine detection limits for ASTM D4929 compliance using Part C methodology and easily meets ASTM D5059 Parts A and C using the Bi internal standard method to measure lead in gasoline samples.
Rigaku NEX XT offers high-level total sulfur measurement (0.02% to 6% S) of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums. This versatile, compact, and robust X-ray transmission/absorption (XRT/XRA) process gauge is specifically optimized for the total sulfur analysis needs of refineries, pipelines, blending operations, bunkering terminals, and other storage facilities.
Also offered is the NEX OL process analyzer for liquid stream applications. NEX OL is configurable for use in classified and non-classified areas and can analyze from aluminum to uranium. It is ideal for monitoring cobalt, manganese, and bromine catalysts in PIA and catalyst in liquid streams.
