Analysis of steel and its alloys usingthe GB/T 20125-2006 standard and an Agilent 5100 ICP-OES in dual view mode Introduction Steel manufacturers conduct quality control testing for a range of metals and trace elements to ensure the gradeand performance of their final product. The Standardization Administration of China uses their GB/T 20125-2006standard“Low-alloy steel - Determination of multi-element contents - Inductively coupled plasma atomicemission spectrometric method" to control the quality of manufactured steel products. Different grades of steelhave different specifications for elemental content， with most steel and stainless steel grades required to have lessthan 0.05 % by weight of Sulfur and 0.04 % by weight of Phosphorus. With the Inductively Coupled Plasma OpticalEmission Spectroscopy (ICP-OES) technique easily able to measure elements at this concentration within a sample，laboratories are looking beyond whether an instrument can ‘do the job’ to whether a specific instrument canimprove their sample throughput， lower their costs， simplify sample preparation and instrument operation， anddeliver reliable results throughout the analysis of a large batch of samples. 2 This application note demonstratesthe performance and benefits of Agilent’s 5100 Vertical Dual View (VDV) ICP-OES instrument in the analysis ofsteel samples， using the GB/T 20125-2006 method. The instrument offers many advantages for this application，which involves the rapid analysis of a large number of challenging steel samples. Agilent Technologies
