Working Principle
The operating principle of the PolySpek Junior is Optical Emission Spectrometry often referred to as ‘OES’. An electrical discharge is applied between the counter electrode and the surface of the prepared metal sample. This is carried out in an argon atmosphere inside the spark-stand and referred to as a ‘spark discharge’. Some of the sample surface material is vaporised releasing the radiation of light at specific wavelengths dependent on the elements present. Light from the spark passes into the spectrometer arrangement of the instrument. Here, CCD (charge coupled device) solid-state detectors measure the relative amplitudes of the different wavelengths of light. Processing of this spectral data yields the analytical results. The analysis program specifies which elements are to appear in the analysis and their concentration ranges. The analytical results appear as percentage values, against each element detected in the sample. Any element outside the programmed limits is highlighted. The values thus indicated should be regarded as estimates only.
