The glass industry is not only interested in analyzing major and minor elements in glass samples, but also in all starting materials, such as sand, carbonate, boric acid, alumina in a solid or liquid form. From this point of view Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) fulfills these requirements, because it provides multi-element analysis with reproducible, reliable results. It is also a very fast technique, with only 2 minutes necessary for measuring 10 elements at various concentrations in a single sample. This study was carried out on a JY 2000-2 sequential spectrometer, which is perfectly suited to this type of sample analysis. 高性能ICP光譜儀
