Our WDXRF Products


Wavelength dispersive X-ray fluorescence (WDXRF) is one of the most versatile analytical methods for elemental analysis of solids and liquids. Elements from boron to uranium can be analyzed in a wide variety of samples with high accuracy, precision and reliability. The technique and the analytical methods are mature enough to establish clear qualitative and quantitative characterization of diversified materials. Modern technological developments have helped to include WDXRF into standard test methods for analytical laboratories (ASTM C114, ASTM D2622, ASTM D6376, ASTM D6443, D7085, ISO 29581, ISO 14596, ISO 14597, ISO 15597) 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.

Cement analysis requirements

The analytical requirements in cement QC laboratories demand elemental analysis for determination of CaO, SiO2, Al2O3, Fe2O3, MgO, SO3, K2O, Na2O, Cl, etc. in raw meal, clinker and cement.

Slag analysis requirements

Slags originate from various stages in the iron and steel making process, e.g. blast furnace, converter, basic oxygen furnace/basic oxygen steelmaking (BOF/BOS), electric arc furnace, or ladle.

Slag has a double role: it permits removal of the gangue and allows exchange reactions with the liquid metal, permitting control of the process to keep the desirable elements in the melt while the others are removed.

The analytical requirements in iron and steel laboratories demand elemental analysis for determination of CaO, SiO2, Fe2O3, MgO, Al2O3, K2O, MnO, Cr2O3, TiO2, P2O5, Na2O and S in slags.

Sulfur analysis requirements

Requests for analysis of sulfur in fuels and oils are increasing as environmental regulations worldwide continue to tighten. Current fuel sulfur standards in some countries already reach as low as 10 ppm, with other countries following. Ensuring 10 ppm or less sulfur at the filling station means producing gasoline or diesel at even lower levels, around 4 ppm.
