Hitachi OE Series Optical Emission Spectrometers (OES)

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.


High-performance metals analysis made affordable

The OE750 and the NEW OE720 are ground-breaking OES metals analyzers. They cover the complete spectrum of elements in metal* with low detection limits and state-of-the-art multi-CMOS technology.

Tightening of industry regulations, complex supply chains and increased use of scrap as a base material means it’s crucial for foundries and metals manufacturers to control main, residual, tramp and trace elements in the lowest ppm range. Historically, OES analysis at this level was out of reach for many businesses. That’s now changed with the OE series.

These spark spectrometers allow you to analyze all main alloying elements and identify exceptionally low levels of tramp, trace and treatment elements in metals, such as nitrogen in steel. The OE750 also covers rare applications like oxygen in copper and oxygen, nitrogen and hydrogen in titanium.

Fast measurement times, high reliability and low operating costs mean the OE series is invaluable for everyday analysis and total quality control, with performance on a par with larger and more expensive spectrometers.
