Ensuring compliance? Why EDXRF is ideal for analysing sulphur, chlorine, metals and more

Could one elemental analyser simplify your compliance and quality control? The petroleum industry faces ongoing challenges in complying with regulatory requirements worldwide. While various methods are used for analysing sulphur and other critical elements, they can be time-consuming and expensive. This is where EDXRF technology could speed up your turnaround times and help streamline your processes to meet ASTM, EPA, and other international test methods.

EDXRF is a cost-effective and trusted technique for compliance testing. Systems are user-installed, self-maintained, and require minimal sample prep. Because of these advantages, EDXRF analysers have become essential tools for many screening and monitoring needs. From quantifying heavy elements in crude oil to sulphur in fuels to various elements in lubricating oils, EDXRF instruments are well-suited for many petroleum-related applications.

Choosing the Right EDXRF Analyser for Your Compliance and Quality Control Needs

Different EDXRF systems are available on the market, but multi-element capabilities make Rigaku EDXRF benchtops stand out. This advantage gives you the flexibility and reliability to monitor sulphur, chlorine, metals, and other elements of interest. This benefit replaces the need for multiple single-element instruments, and you can quickly adapt to new applications. Their capabilities range from ultra-low and trace element concentrations up to percent levels.

Rigaku offers a comprehensive range of budget-friendly EDXRF systems, whether your needs are entry-level or advanced. All systems provide elemental composition data in minutes and do not need ongoing allocations for expensive consumables and maintenance. They are also compact and easily operated with intuitive software that uses a simple flow bar interface for step-by-step setup.

Here is a quick comparison of Rigaku’s EDXRF models, summarsing their exceptional versatility to meet compliance with industry standards and help you stay ahead of evolving regulations:

NEX QC Series – Affordable Systems for Routine QC

How well does your XRF analyser support multi-method compliance? The NEX QC Series are compact multi-element analysers, offering a cost-effective solution for any lab or field application. NEX QC and NEX QC+ models are perfect for smaller labs and field applications because they do not require an external computer. They are ideal for measuring sulphur in oils per ASTM D4294, sulphur in crude, bunker fuel, nickel and vanadium in crudes per ASTM D8252-19, and other petroleum-related applications. NEX QC Series analysers also offer compliance with ISO 13032 for ULSD and lead in gasoline per ASTM D5059.

NEX DE Series – More Performance Capabilities

Are you using expensive commercial standards, or does your process require time-consuming reference material preparation? When you need more performance, NEX DE Series analysers deliver multi-element analysis and reduce standards requirements. Using Rigaku’s Matching Library software, you can easily match your XRF to your actual material. These systems are excellent tools for analysing lubricating oils, perfect for labs developing new formulations or facilities needing ASTM D6481 and ASTM D7751 compliance. NEX DE Series also provide quick ASTM D8252-19 compliance of nickel and vanadium, determining low concentrations of sulphur per ISO 13032, measuring chlorine per ASTM D4929 Part C, and more. You can quickly analyse sulphur, vanadium, iron, and nickel in crude, residual oil, bunker fuels, and other heavy hydrocarbon oils. Additionally, the NEX DE VS model offers small spot analysis for in-plant forensics.

NEX CG II Series – Designed for Complex Applications and Research

Are your applications complex with trace elements and variable base matrices? NEX CG II Series are all-in-one EDXRF systems offering higher sensitivity and trace element detection, making them an attractive choice for commercial labs and R&D facilities. They provide multi-element, multi-application analysis and low limits of detection for multiple testing methods and standards. NEX CG II Series analysers provide ASTM and international compliance performance to test ULSD and meet Tier 3 gasoline requirements per ASTM D7220. You can analyse manganese in MoGas and AvGas at low and ultra-low levels per ASTM D5059 Part D and easily meet ASTM D5059 Parts C and A compliance using the Bi internal standard method to measure lead in gasoline samples. They also deliver the lowest chlorine detection limits for ASTM D4929 Part C.
