FLUORESCENCE X-RAY SPECTROMETRY
The X-ray fluorescence spectrometry allows to perform non-destructive quantitative chemical analysis, extremely fast and accurate on ferrous and non ferrous materials with the classification of the type of alloy according to the international system. This kind of analysis is performed on-site.
METAL FERROUS AND NON FERROUS ALLOYS IN SOLID STATE
All the main alloying elements are provided, excluding carbon.
The analysis should be performed on materials that are likely to contain a substance subject to restrictions in accordance with ROHS regulations.
The analysis procedure for the control of components and materials is divided into two phases:
Phase 1: Analysis of routine that consists of using a technique of analysis such as X-ray fluorescence energy dispersive (EDXRF), which offers a degree of accuracy sufficient to determine:
The presence or absence of Pb, Cd, Cr, Hg or Br; or
The presence of "significant" concentrations of Pb, Cd, Cr, Hg or Br
There are two types of EDXRF:
The portable instrument (X-ray fluorescence spectrometer) is easy to use and enables speed of execution
Step 2: analysis more accurate than necessary under the following circumstances:
Detection of Pb, Cd or Hg concentrations at "borderline", requiring further analysis more accurate.
The method used depends on the material.
Detection of Cr.
Detection of Br
Contact a qualified laboratory as TEC Eurolab in these cases is an appropriate choice.
