Positive material identification PMI-RFA

Positive material identification (PMI) is used to analyse and identify material grade and alloy composition for quality control reasons. It is a quick and mobile non-destructive method, which is used on different assets, products and components as a semi-quantitative chemical analysis.

The X-ray fluorescence analysis (RFA) is one of the most frequently used methods in the field of quality assurance for the qualitative and quantitative determination of the elemental chemical composition of a sample.

This method is mainly applied in the industrial field, for example in installation, apparatus and container construction, shipbuilding, pipeline construction, in foundries, power plants and chemical installations.

Positive material identification PMI – RFA

When it comes to quality assurance, the optical emission spectrometry (OES) is one of the frequently used methods for the qualitative and quantitative determination of the elemental chemical composition of a sample, in which, for example, carbon is one of the characteristic elements. In the OES, a spark is generated on the component under protective gas and the resulting light spectrum is used for the identification of the composition of the active substance by means of a CCD chip. The method is used where slight burn marks on the structural element may be tolerated.

This method is mainly applied in the industrial field, for example in installation, tool, apparatus and container construction, shipbuilding, pipeline construction, in foundries, power and chemical installations.
