OES is carried out in the form of table working place and consists of Spectrometer complete with multi CCD optics facility, spark stand, spark source, spectrometer control, readout system, spark analyzing software and any additional software or hardware to improve the efficacy of the instrument. Compatible PC, peripherals & data control systems.. Spectrometer is the analytical device for elemental analysis of laboratory application which principle of action is based on the atomic- emission spectral analysis with a source of spectra excitation - the generator of the unipolar low-voltage spark in argon. Easy-to-use High reliable instrument for express elemental analysis of all kind alloys of Fe, AL, Cu, Co & Sn bases and etc. with 0,00002% accuracy
