ANALYTICAL INSTRUMENTATION
Faster, easier elemental analysis for every petroleum application Fuel Analysis
Every petroleum product, from heavy crude oils to fi nished fuels, depends on reliable elemental data. But too often, that analysis comes with long turnaround times, complex sample prep, and higher operating costs.
Rigaku’s NEX series energy dispersive X-ray fl uorescence (EDXRF) analysers are designed to change that. Whether you are running daily quality checks, tracking trace metals, or monitoring real- time blending, the NEX line delivers reliable results without the trade-offs. They are purpose-built for petroleum applications.
When you need fast answers for daily QA/ QC, the NEX QC Series provide multi-element performance in one compact system. Designed for affordable routine analysis, it measures sulphur and other key elements across crude, fuels, and other products. No external computer is needed. Complies with: ASTM D4294, D8252-19, ISO 13032, ASTM D5059. Best for: Field labs and facilities that need quick, dependable verifi cation.
When your lab demands high performance, but you do not want to wrestle with calibration standards, the NEX DE Series analysers deliver. Its Rigaku Matching Library software reduces standards requirements and easily handles high-throughput multi-elemental analysis for sulphur, chlorine, nickel, vanadium, and other key elements across a range of petroleum samples. Additionally, the NEX DE VS model is perfect for in-plant forensics using small spot analysis.
Complies with: ASTM D4294, ASTM D8252-19, ISO 13032, and ASTM D4929 Part C. Best for: Refi neries, midstream labs, and QA teams who need rapid, reliable precision.
For researchers and commercial labs, the NEX CG II Series is your all-in-one benchtop for trace-level elemental analysis. Using indirect excitation with secondary targets, it achieves exceptional sensitivity, even with variable base matrices. Additionally, you can create your own Matching Libraries to tailor calibrations for your unique needs and formulations, all
within an intuitive software interface that saves you time and reduces costs. The NEX CG II Series complies with: EPA Tier 3 and ASTM D7220 for ULSD sulphur, ASTM D5059 Parts A and C for lead using the Bi internal standard method, ASTM D5059 Part D for manganese at ultra-low levels, and ASTM D4929 Part C for chlorine, where it delivers the lowest detection limits in its class. Best for: Commercial testing labs, research facilities, and advanced QA environments that require trace-level precision.
When you want to reduce sampling requirements for the lab, Rigaku’s on-line analysers bring continuous monitoring to your process lines. These systems help you cut sampling time, spot upset conditions instantly, and keep your processes running in spec.
The NEX XT provides real-time total sulphur measurement from 0.04 to 6 wt% for various petroleum streams such as crudes, bunker fuels, fuel oils, and other viscous hydrocarbons, including residuums. The NEX XT is ideal
for refi neries, pipeline monitoring, blending operations, bunkering terminals, and other storage facilities.
For multi-element analysis of liquid streams, the NEX OL is recommended for monitoring cobalt, manganese, and bromine catalysts in PTA and catalysts recovery processes.

Mercury and Petrochemicals P S Analytical – Experience, Performance, Reliability and Support
The presence of mercury (Hg) in petrochemical samples is very bad news. Even at ultra-low concentrations mercury is corrosive to gas plant components and infrastructure, poisonous to expensive downstream precious metal catalysts and exposes workers to highly toxic workplace conditions.
Gas Analysis
Upgrade hazardous area process control and reliability
The analyser enhances process control by delivering high-precision measurements, from ppm levels to percentages. This enables optimization of processes improving operational effi ciency and the safety of people and environments.
Servomex has upgraded the SERVOTOUGH SpectraExact 2500F, a new fl exible gas and liquid water analyser for hazardous areas. The innovative analyser is IEC Ex approved and meets compliance requirements across Europe, the USA and Canada. It provides highly accurate data while reducing maintenance needs and costs. Its digital communication systems ensure seamless integration, making it the ideal upgrade for current Xendos 2500 and SpectraExact users.
The SpectraExact 2500F is designed to offer a fl exible analytical solution adaptable to a range of applications and hazardous areas. The rugged build allows analysis of toxic, fl ammable or corrosive samples without damage to equipment or the environment. Wall-mounting options enable fl exible placement, even in the harshest of conditions.
Rhys Jenkins, IP&E Spectroscopic Product Manager, said: “The SpectraExact 2500F delivers a winning combination of proven performance and fl exible operation in a resilient and reliable design.”
Users can expect increased uptime and reduced ongoing costs thanks to non- depleting, NDIR sensing technologies that extend calibration intervals. Servicing is simple, with a removable sample cell that is separate from the electronics, making scheduled maintenance quick and easy.
Rhys Jenkins added: “The ability to reduce ongoing costs and leverage maximum process effi ciency is important in many harsh environments or hazardous areas. This is why the SpectraExact 2500F features an intelligent design that makes maintenance easy.”
As the latest edition to Servomex’s SpectraExact range, the 2500F offers a direct upgrade for existing 2500 users. Digital communication systems ensure smooth integration with existing setups, while enhanced usability provides rapid response times and simplifi es data access.
Real-time data can be monitored remotely, further improving safety and effi ciency.
The SpectraExact 2500F boosts uptime, reduces maintenance costs and futureproofs your processes.

It’s no wonder that petrochemical plants and refi neries spend vast sums every year removing even small concentrations of Hg from their precious gas and liquid sample streams. It is also no wonder that they wish to maximise the effi ciency of their Hg removal systems and to achieve this, highly accurate and sensitive monitoring and measurement of Hg is required. Sub part per trillion sensitivities is the normal requirement.
That’s where P S Analytical (PSA) comes in.
For over 40 years PSA has been at the forefront of trace Hg determinations. PSA partners with many companies to monitor and help manage this Hg removal process. This partnership happens from the research bench through to production with PSA taking a pivotal role in ensuring successful removal technologies are deployed in the real world.
PSA have analysers to suit all aspects of the monitoring and analysis of Hg, including laboratory instruments and on-line analysers for gases and liquids. More recently PSA have provided solutions for speciation (fractionation) analysis and also waste water systems associated with petrochemical processes.
Employing Atomic Fluorescence Spectroscopy as the means of detection the PSA analysers provide ultimate detection performance. With literally thousands of systems in the fi eld today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.
