Stationary 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.

Our customer stories 

Köster und Co. GmbH: "We chose the FM EXPERT to have a cost-effective solution to analyze nitrogen at low detection limits."

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.

If you are interested in more information, please read our blogs Automated charge correction with OES analysis and Software solution ensures charge correction without the complication.

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.
