前言作为向国庆二十周年献礼,我们于1965年7月开始研制晶体管化火花源双聚焦质谱仪。在毛主席“独立自主、自力更生”方针指引下,于1969年9月试制成功了这台仪器,四年多来,共分析了20多种试样,性能良好。仪器的试制质谱分析的基本原理是:将试样电离成为离子,在加速电场作用下,离子流进入磁场(或电场和磁场的组合),在磁力作用下不同质荷比的离子将有不同的运动轨
Preface As a tribute to the twentieth anniversary of the National Day, we began in 1965 July the development of transistor-based spark source dual-focus mass spectrometer. Under the guidance of Chairman Mao’s principle of “independence and self-reliance”, the instrument was successfully trial-produced in September 1969. Over the past four years, a total of more than 20 samples were analyzed and the performance was good. The basic principle of mass spectrometry analysis of the instrument is: the ionization of the sample into ions, accelerated by the electric field, the ion flow into the magnetic field (or a combination of electric and magnetic fields), different magnetic properties of ions with different mass-to-charge ratio will have different Track
