The Optical Emission Spectrometer represents a new class of metal analyzers distinguished by improved analytical performance, greater investigative flexibility and simpler operation. The group of components that is most important for analysis excitation source, optics and read-out system is optimally adapted to each other; it is the superior analytical core of the new generation of arc/spark analyzer that combines performance and flexibility. This machine consists with a special attachment to check thin sheets and small rods. This new analyzer allows the accurate analysis of all main components and trace elements in steel, iron, aluminium, copper and zinc at this movement
