Optical Emission Spectrometer

Optical Emission Spectroscopy (OES) , also known as spark testing,  is a well-known tecnique for the elemental analysis of the ferrous and not ferrous alloys. The optical emission spectrometer can be used as Metal Analysis Spectrometer, which is widely used in various indusries, such as iron and steel, non-ferrous metal, metallurgy, machinery, chemical equipment, quality inspection system and so on. It is also used in , routine identification and analysis in metallic smelt industry.

Allocating and analyzing channel and quantitative work scale Major Features

  1. The human oriented design, the standardized and modularized manufacture make the apparatus smaller.
  2. The core components are all imported, which strengthen the stability and reliability of the apparatus.
  3. We adopt the advanced foreign technologies of excitation source and design the excitation source of high energy, high stability by our own to fulfill the needs of ultrahigh content and trace analysis.
  4. It adopts overall exit slit using technology which is convenient for choosing passage and regulating.
  5. The high voltage of the PMT in the apparatus is controlled directly by computer and regulated by software, which improved efficiency of the passage.
  6. In the apparatus, there is an automatic constant temperature system which solve the problem of bad effects to the optics system caused by changing temperature.
  7. The multi-language operation software and flexible configuration enable the apparatus more humanistic.
  8. This apparatus can analyze various kinds of matrix, such as Fe, Co, Ni, Ti, Cu, Al, Pb, Mg, Zn and Sn.
