Analysis of Oxygen (O) and Nitrogen (N) in Metal 3D Printer MaterialsStainless steel, Ti, Al, and Cu are commonly used as metal 3D printing materials, and customers have expressed a desire to be able to quickly manage the amounts of oxygen (O) and nitrogen (N) in those materials. For example, if the Ti material contains a large amount of oxygen (O), oxides will be produced, which can lead to defects in the printed part.
使用 MESA-50 对钢涂层进行无损的厚度和成分分析钢涂层在防止钢腐蚀方面起着重要作用,因此了解涂层有助于改善钢的性能。XRF 是一种用于测量涂层厚度和成分的强大技术,使用 MESA-50 X射线荧光分析仪对钢上的锌镍涂层进行了无损的厚度和成分分析。
Analysis of ultra-trace amounts of sulfur in metalAs the steel materials are becoming more sophisticated, such as natural gas or crude oil pipeline, sulfur content is recommended below 0.5 ppm. Hence, more accurate ultra-trace amount sulfur analysis is required. Analysis of trace amount of sulfur in steel materials can be done quickly with the conventional combustion-infrared absorption method, but the problem is that the sensitivity of the detector is insufficient and it can not be measured.
使用便携式 EDXRF MESA-50 快速、轻松和安全地控制锌镍电镀槽由于配备了专用样品池,EDXRF 技术不仅可用于固体元素分析,还可用于电镀溶液等液体分析,这个案例通过表征 Zn-Ni 镀锌浴的降解来展示MESA-50 对电解浴的跟踪能力
钢和金属中氢的分析:固体抽取或熔融EMGA系列中的氢分析仪用于精确测量不同类型样品中的氢含量,如黑色金属、有色金属、半导体或电子材料。通过在惰性气体中加热熔融样品并抽取释放的氢气,再通过高灵敏度热导检测器进行分析即可得到氢的精确含量。但也可以在低于样品熔点加热的方式,在不熔融样品的情况下抽取释放的氢气从而测定氢含量。本内容是解释何时使用熔融抽取,何时使用固体抽取,其有利之处、具体应用和对应的样品。
