The first two methods can analyze a single element, and the operation is complicated, time-consuming and laborious, and the efficiency is low; photoelectric direct reading spectrometry can analyze multiple elements at the same time, and the operation is easy, but it can only analyze block samples. ICP-OES has the advantages of ...
Optical Emission Spectroscopy (OES) is a relatively simple technique that allows you to measure the steel directly without extensive preparation or the use of harsh chemicals. ...
The new OE750 OES analyser from Hitachi High-Tech shows what’s possible with an analyser of this class. It has the performance usually only seen in much more expensive instruments, such as analysing all elements in metal down to astonishingly low ppm. But how can it deliver this level of performance at such an accessible purchase price? And how have we cut the analyser’s running ...
There’s never been a more demanding time for those in the metals industry. Foundries and steel plants are under increasing pressure to use scrap materials in the melt. Supply chains are getting more complex and perhaps less reliable. Legislation for trace elements is getting ever tougher. The result is that to be able to consistently produce a profitable, high quality product that meets all ...
Without confidence in your measurement system, you simply cannot be sure that your parts meet specification. Whether gauging composition or measuring thickness, out of spec parts result in rework, extra scrap, in-field failure and potential reputational damage. Internationally recognised quality management systems (QMS) call for measurement system analysis (MSA) procedures. This means you ...
To produce a sound casting in a foundry, the melt must have the right composition of specified grade metallic and non-metallic elements. Good foundry practices, including careful melt preparation and mould design, can help to avoid defects. However, depending on the source materials (raw material, sorted scrap or leftovers from previous melts) a procedure to refine or correct the composition ...
Abstract In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated. ...

The laboratory employs and combines diverse techniques such as chromatography (LC, GC, SEC/GPC, IC), mass spectrometry (LC/MS, GC/MS, MALDI-ToF,ToF-SIMS, ICP/MS), failure analysis, thermal analysis, rheology and spectroscopy (NMR, FTIR, Raman, NIR, ICP-OES, XRF, XPS) to analyze polymers, catalysts, surfactants, ceramics, nanomaterials, semiconductors, and medical ...
