On-line, Real-time Analysis by Energy Dispersive X-ray Fluorescence (EDXRF)

NEX OL
NEX OL

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 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 to Uranium

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.

A Broad Range of Applications

XRT Applications




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

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.
