Stationary Optical Emission Spectrometers

Seamless quality control is essential for any metalworking, starting with tramp element analysis for scrap, inspection of in-coming materials, QA / QC in the foundry process and goods issue.

Optical Emission Spectroscopy, or OES, is a well trusted and widely used analytical technique used to determine the elemental composition of a broad range of metals.

Our stationary optical emission spectrometers offer the highest levels of accuracy and precision of the analytical results. A powerful yet easy-to-use software package covers almost every application.

Why Hitachi High-Tech´s stationary OES Analysers?

Low detection limits of a wide range of elements

  • Analyse the majority of metals and their alloys, even critical trace tramp and inoculating elements
  • Widest spectral range covering nearly all interesting elements, including Nitrogen in steel
  • Integrated grade database
  • Results at your fingertips: wide range of result forms, automatic storage

High analytical performance using robust yet reliable technology

  • Very short start-up and measurement time
  • Sample stand accessible from three sides
  • High resolution detector for best spectral line separation
  • Extensive result, report and result processing options
  • Excellent long-term stability, ensured by peak position alignment (PPA)
  • Continuous use, even in rugged conditions

Charge Correction

This optional software automatically calculates the right quantity of material to add to a melt to bring it into spec. You no longer have to rely on human expertise and it greatly speeds up the charge correction process. The software also calculates the most cost-effective way to correct the melt by considering your available source material and furnace capacity.

Statistical Process Control

The optional SPC allows you to easily monitor your processes and notifies you if your melt, process or instrument is out of spec. You can set an upper and lower control limit for each element and see a visual representation of each element within those limits over time. This means you can reduce scrap and rework by spotting trends before they impact the final specification. On top of this, traceability functionality makes it easy to provide information
for customer or regulatory audits.
