一、前言 真空熔融微压法测定金属中的氧,是大家比较熟悉的一个经典方法,分析可靠性较好,但分析速度较慢,设备庞大,操作烦复。为了适应科研工作的需要,许多科技工作者将该法作了很大的改进,并同其他检测手段结合起来,形成了真空熔融—红外分析法、碳弧熔化—气相色谱法、真空熔融—气相色谱法等新技术。中国科学院大连化学物理研究所于63年应用真空熔融—气相色谱法成功地测定了金属中的微量气体,冶金部钢铁
I. Introduction Vacuum melting micro-pressure determination of oxygen in the metal, we are more familiar with a classic method, the analysis of good reliability, but the analysis speed is slow, the device is huge, the operation annoying. In order to meet the needs of scientific research, many scientists and technologists made great improvements to this method and combined it with other testing methods to form vacuum melting-infrared analysis, carbon arc melting-gas chromatography, vacuum melting-gas phase Chromatography and other new technologies. Dalian Institute of Chemical Physics, Chinese Academy of Sciences in 63 years by vacuum melting - gas chromatography successfully measured the trace gases in the metal, the Ministry of Metallurgical Steel
