ARL™ OPTIM’X WDXRF – Spectrometer

Meet demanding materials analysis requirements with qualitative and quantitative characterization of all types of conductive and non-conductive unknown samples. The Thermo Scientific™ ARL™ OPTIM’X WDXRF Spectrometer provides all the benefits of wavelength dispersive x-ray fluorescence (WDXRF), one of the most versatile methods for elemental analysis of solids and liquids. The system is available in four preconfigured packages specifically suited for analysis in the petroleum, cement and slags industries or for multi-purpose requirements in analytical laboratories.

The ARL OPTIM’X WDXRF Spectrometer analyzes elements from carbon to uranium in a wide variety of samples with accuracy, precision and reliability. WDXRF is a standard test method for analytical laboratories (ASTM and ISO norms for example) by virtue of its simplicity, flexibility, affordability and reliability. The cost per analysis is clearly advantageous over many traditional wet chemical and other spectroscopic methods.

  • Analysis of sulfur (S) and other elements in petroleum products and lubricants, fully compliant with ASTM, ISO and other industrial WDXRF norms
  • Major and minor oxides in raw materials such as limestone, sand, bauxite, ceramics, refractories, slags and sinters
  • Major and trace elements and contaminants in food and chemical products
  • Unique WDXRF platform with sequential and/or simultaneous capabilities
  • 500W equivalent analytical performance from 200W X-ray power
  • 200W equivalent analytical performance from 50W X-ray power
  • Element coverage from carbon to uranium, depending on configuration
  • High precision (short term and long term repeatability) thanks to temperature regulation of spectrometer and crystals
  • Superior spectral resolution from low Z elements to heavy elements (∼15 eV at CaKα)
  • Stand-alone and autonomous operation without water cooling
  • No gas supply required (depending on the configuration)
  • Simple and direct sample introduction
  • Automatic analysis of batches with sample changer
  • Small footprint

Many sample types can be analyzed including conductive or non-conductive solids, liquids, loose powders, pressed pellets, fusion beads, pastes, granules and coatings.

  • Innovative UCCO technology (Ultra Closely Coupled Optics) for increased intensity, up to 210% higher than conventional geometry
  • Unique compact SmartGonio device for sequential analysis
  • Optional Multichromators for faster analysis or better performance on selected elements
  • Optional OptiQuant package provides “standard-less” analysis for up to 73 elements when specific standards are not available, or when samples can only be obtained in small quantities or as irregular shapes
