原子吸收光度法是仪器分析中的一项新技术,它可应用于冶金、农业、石油、地质、化工、医药、生物等各部门。具有灵敏度高,干扰少,测定迅速,成本低等优点,几乎能测定全部金属元素。这种仪器必需具有一种能发射欲测元素原子谱线的光源,而且要求谱线宽度窄,稳定性高,发射强度大。空心阴极灯就是根据这些条件和要求设计和制作的。在毛主席无产阶级革命路线的指引下,我们遵照毛主席关于“我们必须打破常规,尽量采用先进技术,在一个不太长的历史时期内,把我国建设成为一个社会主义的现代化的强国。”的伟大教导。狠批反革命修正主义科研路线,几年来我们边试验,边总结,试制成功了30多种空心阴极灯,其中包括碱金属和碱土金属的元素灯。某些需用氧化亚氮气体测定的元素灯虽没有试制,但估计问题也不大。空心阴极灯的制备成功是对“洋奴哲学”与“爬行主义”的修正主义科研路线的有力批判。本文详细地介绍了空心阴极灯的制做方法,内容共分四个部分:一、一般原理;二、灯的设计和制造工艺;三、真空——充气装置和操作流程;四、灯的检查。重点介绍二、三部分,其中包括灯形,阴极的不同加工方法,阳极材料,阴极的屏蔽,吸气材料,充入气体与强度的关系,制灯用电源,真空——充气装置和操作流程等。为了较快地掌握制灯工艺,还介绍了空心阴极灯的结构原理。我们制备的空心阴极灯的主要技术指标,如发射强度,背景,稳定性以及灵敏度等都达到了国外进口同类型灯的水平。灯的性能满足了原子吸收光度法的要求。由于水平有限,错误和不当之处一定不少,希提出批评和指正。
Atomic absorption spectrometry is a new technique in instrumental analysis. It can be applied to various departments such as metallurgy, agriculture, petroleum, geology, chemical industry, medicine and biology. With high sensitivity, less interference, rapid determination, low cost, almost all the metal elements can be measured. Such an instrument must have a light source that emits the line of atoms of the element to be measured, and requires a narrow spectral width, high stability, and high emission intensity. Hollow cathode lamp is based on these conditions and requirements of design and production. Guided by Chairman Mao’s proletarian revolutionary line, we follow Chairman Mao’s statement: “We must break the routine and try to adopt advanced technologies to make our country a modern socialist power in a not too long historical period.” Great teaching. In the past few years, we conducted experiments and summarized and piloted more than 30 kinds of hollow cathode lamps successfully, including the elemental lamps of alkali metals and alkaline earth metals. Some need to use nitrous oxide gas to determine the elemental lamp although not trial, but the estimated problem is not large. The successful preparation of hollow cathode lamps is a powerful criticism of the revisionist scientific research line of “Western Slavery Philosophy” and “Creepism”. This article describes in detail the method of making hollow cathode lamp, the content is divided into four parts: First, the general principles; Second, the lamp design and manufacturing process; Third, the vacuum - inflatable devices and operating processes; Fourth, the lamp inspection . Focus on the second and third parts, including the lamp, the cathode of different processing methods, anode material, cathode shielding, getter material, filled with the relationship between the intensity of gas, lamp power, vacuum - inflatable devices and operating procedures Wait. In order to quickly grasp the lamp making process, also introduced the structural principle of hollow cathode lamp. The hollow cathode lamp we prepared the main technical indicators, such as emission intensity, background, stability and sensitivity have reached the level of foreign imports of the same type of lamp. Lamp performance to meet the requirements of atomic absorption spectrometry. Due to the limited level, there must be a great deal of errors and misconduct, and Xi proposed criticism and rectification.
