NEX OL


NEX OL Process Elemental Analyzer
On-line, real-time analysis by Energy Dispersive X-ray Fluorescence (EDXRF)


Featuring advanced 3rd generation energy dispersive X-ray fluorescence (EDXRF) technology, the Rigaku NEX OL represents the next evolution of process elemental analysis for liquid stream and fixed position web or coil applications. Designed to span from heavy industrial through to food grade process gauging solutions, the NEX OL is configurable for use in both classified and non-classified areas.

Analyze from aluminum (13Al) to uranium (92U)
To deliver superior analytical performance and reliability, the EDXRF measuring head assembly was derived from the established Rigaku NEX QC+ high resolution benchtop instrument. With this proven technology, the Rigaku NEX OL delivers rapid, non-destructive, multi-element analyses – from parts-per-million (ppm) levels to high weight percent (wt%) concentrations – for elements from aluminum (13Al) through uranium (92U). Equipped with a 50 kV X-ray tube and SDD detector – together with a standardized, optimized suite of tube filters – the Rigaku NEX OL is engineered to solve a broad range of process control applications.

Unique toolless flow cell design
For the elemental analysis of liquid streams, an analyzing head is mated to a unique toolless flow cell assembly incorporating the X-ray window . The X-ray window contains the liquid stream but is transparent to X-rays; it is typically a plastic film.

Coating thickness and composition
In addition to analyzing liquid streams, the Rigaku NEX OL is designed to service web and coil applications, with the ability to perform multi-element composition and/or coating thickness. Typically a head is mounted in a fixed position over a roller so that the head to surface distance is constant.

    NEX XT Total Sulfur Process Analyzer


    Advanced X-ray Transmission / Absorption (XRT/XRA) Total Sulfur Gauge for Crude Oil, Marine Bunker Fuel and Blending Operations

    Rigaku's NEX XT is the next generation process gauge for high-level total sulfur measurement (0.02% to 6% S) of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums.

    On-Line total sulfur gauge
    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. Applications for the NEX XT include bunker fuel blending to meet MARPOL Annex VI sulfur restrictions, interface detection of different grade fuels delivered via pipelines, refinery feedstock blending and monitoring, and the quality monitoring of crude at remote collection and storage facilities.

    Measure sulfur (S) from 200 ppm to 6 wt%

  • Compact design with no routine maintenance
  • Up to 1480 psig and 200°C
  • User adjustable data update frequency
  • Reduced standards requirements
  • No sample condition or recovery system
  • No radioisotopes

  • Applications
    Pipelines, Upgrading Facilities and Refineries
    This versatile, compact and robust X-Ray Transmission (XRT) process gauge was specifically optimized for the total sulfur analysis needs of refineries, pipelines, blending operations, heavy oil upgrading, bunkering terminals and other storage facilities.

    Applications include bunker fuel blending to meet MARPOL Annex VI sulphur restrictions, interface detection of different grade fuels delivered via pipelines, refinery feedstock blending and monitoring, and the quality monitoring of crude at remote collection and storage facilities.

    MARPOL Regulations
    IMO ship pollution rules are contained in the "International Convention on the Prevention of Pollution from Ships", known as MARPOL 73/78. On 27 September 1997, the MARPOL Convention was amended by the "1997 Protocol," which includes Annex VI titled "Regulations for the Prevention of Air Pollution from Ships". MARPOL Annex VI sets limits on NOx and SOx emissions from ship exhausts and prohibits deliberate emissions of ozone depleting substances. The Rigaku NEX XT is the perfect tool to assay marine bunker fuels for blending to meet emissions regulation compliance.

    3rd Generation Technology
    The new Rigaku NEX XT system is faster, more sensitive and far more compact than competitive systems and provides continuous, reliable detection of sulfur at pressures up to 1480 psig and 200ºC. Rigaku NEX XT can operate as a stand-alone analyzer or provide real time closed loop control when tied into a blending or plant wide automation system.

    Among its other key features are a simplified user interface, reduced standards requirement, automatic density compensation, automatic water compensation, password protection, and standard platform for communicating sulfur, density, and water content to a plant-wide DCS. Due to its unique design and robust construction, sample conditioning and recovery systems are typically not required.
