The Laboratory of spectrometric analysis possesses atomic-emission spectrometer Spectrolab M3 with inserted computer.
By the spectrophotometer Spectrolab M3 used, examinations can be performed both of final castings or metal scrap and of express samples taken in the process of metal melting in order to correct the composition of the casting alloy.
The optical atomic-emission spectrometric analysis is based on determination of the chemical elements concentrations by means of their atomic emission spectra. After sample sparkling when the intensities of the analytical lines of the determinable elements are automatically measured the display shows the values of the corresponding concentrations.
Depending on the individual requirements, examinations of the composition of iron, copper and aluminum based metals can be made.
The determinable elements and the determination limits with the respective indefiniteness are:

The apparatus has unique optical system which contains two different spectral modules assembled in one body whose signals are processed simultaneously. This provides the advantage to analyze simultaneously elements in vacuum and air optics.
The analyses are performed on the basis of large quantity various certified reference materials on iron, aluminum and copper base delivered by renowned producers.
The traces left on the sample surface are comparatively small and its integrity is not broken.
The Laboratory issues protocols in compliance with BDS EN ISO / IEC 17025.
