Monitoring and controlling the level of trace element impurities in metals and alloys is important, as impurities can affect the properties of the metal and may degrade the functionality of the finished component. ICP-OES is commonly used for the routine measurement of trace elements in metal samples because of its multi-element capability and tolerance of the high matrix level present in metal sample digests. However, the development of high purity metals and higher-performance alloys requires stricter control of a wider range of trace elements at lower concentrations, so a technique with lower detection limits than ICP-OES is required. ICP-MS offers low detection limits for the elements of interest, but the technique has not previously been considered suitable for the analysis of high matrix samples such as metal digests. For example, conventional ICP-MS instruments may suffer from signal suppression and/or long-term signal drift due to matrix deposition on the interface cones, which affects the signal stability and the accuracy of the analytical results. To overcome this limitation, Agilent’s Ultra High Matrix Introduction (UHMI) aerosol dilution technology has been developed to allow the

Steel manufacturers conduct quality control testing for a range of metals and trace elements to ensure the grade and performance of their final product. The Standardization Administration of China uses their GB/T 20125-2006 standard “Low-alloy steel – Determination of multi-element contents – Inductively coupled plasma atomic emission spectrometric method” to control the quality of manufactured steel products. Different grades of steel have different specifications for elemental content, with most steel and stainless steel grades required to have less than 0.05 % by weight of Sulfur and 0.04 % by weight of Phosphorus. With the Inductively Coupled Plasma Optical Emission 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 can improve their sample throughput, lower their costs, simplify sample preparation and instrument operation, and deliver reliable results throughout the analysis of a large batch of samples. 2 This application note demonstrates the performance and benefits of Agilent’s 5100 Vertical Dual View (VDV) ICP-OES instrument in the analysis of steel 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.

对于管线钢拉伸试验,我们最受欢迎的系统为工业系列1000HDX。为了操作简便、提 高安全性、保证样品夹持时不打滑,我们建议采用全开放液压夹具配置。对于管线钢测试, 我们建议使用我们的多功能 Bluehill® 3 软件,其中已根据 ISO 6892-1 和 A370标准预先进 行了试验方案的设置,满足 API5L/ISO 3183的要求。

我们发现,视频引伸计在这些试验中应用不多,因为金属行业中大多数用户采用传统的 接触式引伸计并相信其结果的可靠性。引伸计技术的发展为金属测试用户提供了其他选择, 例如我们的先进视频引伸计(AVE).该方案不仅允许同时采集轴向和横向应变数据,并减少 因刀口的磨损和撕裂所需的维护,还提高了效率、简化了测试。本测试的目的是为了演示采 用 AVE 测试钢样品的准确性和可靠性。为此,我们采用5982万能试验机、10kN 的载荷传 感器和50kN 的带齿面的楔型夹具。我们采用 Bluehill® 材料测试软件获得试验结果。
