XRF Spectrometer ARL OPTIM’X from Thermo Scientific

For the elemental analysis of solids and liquids, the wavelength dispersive X-Ray fluorescence (WDXRF) method is a very adaptable analytical approach. With great accuracy, precision, and dependability, a variety of samples including elements from beryllium to uranium may be examined.

Salient Features

The following are the notable features of the ARL OPTIM’X:

  • No gas supply is needed
  • Direct and simple introduction of the sample
  • Unique compact SmartGonio for sequential analysis
  • Sequential-simultaneous configuration blending speed with analytical flexibility
  • High accuracy, both short-term and long-term repeatability due to temperature regulation of spectrometer and crystals
  • Superior spectral resolution from low atomic number elements to heavy elements (~15 eV at CaKa)
  • Optimum configuration for specific applications with simplified operation, which is compliant with ISO and ASTM standards
  • Stand-alone and autonomous operation without the need for water cooling
  • Automatic analysis of batches with sample changer
  • Small footprint
  • Innovative WDXRF platform with simultaneous and/or sequential capabilities
  • Element coverage from fluorine to uranium, based on the configuration
  • Innovative Ultra Closely Coupled Optics (UCCO) technology for increased intensity, up to 210% more than conventional geometry
  • Multichromators for rapid analysis

The following elements of the ARL OPTIM’X can be customized for speed and flexibility:


  • 50 W basic or 200 W optional power to achieve 2.5 times faster analysis
  • Sequential-simultaneous analysis: SmartGonio and 2 elements simultaneously on one multichromator
  • Up to 8 elements simultaneously using 4 multichromators
  • Sequential analysis with the SmartGonio


The ARL OPTIM’X may be set up for a variety of uses, such as:


  • Food industry for major and minor nutrients and other regulated elements
  • Major and minor oxides in products such as sanitary ceramics, refractories, slags and sinters
  • Glass, paints, paper, ferro-alloys, silicon, metal sheets and other products where a few major and minor elements need to be monitored
  • Major and minor oxides in raw materials such as limestone, sand, feldspar, bauxite, magnesite and other mining applications
  • Petroleum industry: The analysis of S (ISO 14596 or ASTM D2622), Pb (ASTM D5059) or other elements in gasoline, fuels and oils
