WDXRF spectrometer

Description

X-ray fluorescence is a fast and non-destructive analysis method for the determination of the chemical composition of all kinds of material. (solid, liquid, powder) Qualitative and quantitative analysis with standard less software provides quick quantification of element concentrations. Possible to measure the elements  F- U.

Applications

  • Chemical composition of unknown solid crystalline materials to be able to identify structures with XRD.
  • Identification and characterization of elements in crystalline substances such as scorodite, struvite and magnetite.
  •  Verify the presence of (metal) catalysts and polymer additives (e.g. stabilizers, pigments, etc.) in polymers.
  •  Quantification of catalyst residue in (intermediate) products.
  • Verify leaching of metal particles into reaction media or other (aqueous) solutions.
  • Element composition of noble/transition metal based catalysts and their supports (carbons and metal oxides)
  • Identify metals and other inorganic particles in plastics.
  • Analysis and identification of inorganic matter in biomass (e.g. silicates in straw/grasses, etc.).
  •  Identification and quantification of residual metal in lignin and carbohydrate samples.
  • Quality of food and nutrition products.
  • Elemental composition of minerals and ores.
  • Analysis of impurities.
