On-line, real-time analysis by Energy Dispersive X-ray Fluorescence (EDXRF)
Features and benefits
Real-time process control by elemental analysis
Measure elements (₁₃Al to ₉₂U)
From ppm levels to weight percent (wt%)
Robust NEX QC⁺ optics with SDD detector
Industrial touch screen user interface
Easy empirical calibration and routine operation
Toolless routine maintenance
Multiple remote analysis heads (non-classified)
No dangerous radioisotopes
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 (Al) through uranium (U). 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.

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.
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. Some of the most common applications include:
Polyethylene / PET manufacturing: TPA and PTA catalysts
Metal finishing: plating, pickling and pre-treatment baths
Mining: solvent extractions
Chemicals: blending additives and resins
Paper and plastics: release / barrier coatings, fire retardants, UV stabilizers
Woven and nonwoven fabrics: fire retardants, UV stabilizers
Metals: conversion coatings, other surface coatings
Petroleum: lubricating oil additives and blending
Pulp and paper: process water
Industrial: waste water
Rigaku NEX OL for Liquid Streams or Web Applications
How It Works
With X-ray fluorescence (XRF), an electron can be ejected from an inner atomic orbital by the absorption of light (photon) from an X-ray tube. An electron from a higher energy orbital transfers to fill the vacant orbital. During this transition, a photon may be emitted. Because the energy difference between two specific orbital shells is always the same for a specific element, the emitted photon will always have a unique characteristic energy (keV). At any characteristic energy, the number of photons per unit time (counts per second) detected is correlated to the concentration of that element in a process stream.
Rigaku Delivers Superior Performance Without Dangerous Radioisotopes
Globally, the petroleum industry continues to employ tens of thousands of radioisotopes in activities that range from exploration and production to distribution. The presence of these radioisotope sources, in such vast numbers, represents a statistically significant opportunity for theft and subsequent misuse. Governments worldwide now regard radiological terrorism, through the use of radiological dispersive devices (RDD) - often called "dirty bombs," to be far more likely than use of a nuclear explosive device. In the context of the recent Deepwater Horizon Incident in the Gulf of Mexico, it is incumbent on the petroleum industry to evaluate liability exposure relative to its radioisotope inventory. Whether protecting the customer base or corporate shareholders, technology now exists to largely mitigate the risk associated with previous generation isotope-based technologies.
