Hitachi FM Expert Optical Emission Spectrometer

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, melt control 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, with state-of-the-art CMOS and CCD technology. A powerful yet easy-to-use software package covers almost every application.


Low level nitrogen analysis

The FM EXPERT is the next level optical emission spectrometer, combining superior analytical performance with a compact size. Its large wavelength range is ideal for the analysis of all relevant elements in metals quality assurance and production process control. The FM EXPERT also allows for the analysis of nitrogen at low levels thanks to its compact CCD optics system.

The FM EXPERT combines our patented smart optics with an improved plasma view, guaranteeing excellent analytical performance with low detection limits over the entire wavelength range. The argon purged optics reduce maintenance intervals and the costs of ownership. Unique in its class, the FM EXPERT’s sealed argon system for optimized optical plasma view and the concentric electrode shielding argon flow ensure reliable nitrogen analysis down to a detection limit of just 30 ppm.

Importance of Nitrogen Analysis
  • High nitrogen content in steel may result in
    • Inconsistent mechanical properties
    • Embrittlement of heat affected zone of welded steels
    • Poor cold formability
    • Strain aging
    • Formation of pin holes during casting
Highlights and applications
