新型脉冲加热气相色谱金属中H、N、O测定仪

摘要

选用先进可靠的国产仪器零部件，设计组装一台新型自动化的脉冲加热气相色谱仪，具有在同一台仪器上准确测定金属中N、O和H含量的独特功能，成功应用于硬质合金和难熔金属及其碳化物中N、O和H的生产分析，并能推广应用于金属陶瓷材料中N、O和H含量的测定。%electing advanced and reliable instruments and components made in China, a new type of impulse heating- gas chromatograph determinator is designed and assembled. It has unique function of accurately determining H,N,O in metals and has been used in production analysis of H, N,O content in cemented carbides,refractory metals and their carbides. It can also be used in measuring H,N,O content in metal ceramics.
