原子吸收光谱分析是从本世纪五十年代以来发展的一种新的分析方法。这种方法灵敏度高、选择性好、操作简便、适用范围广。在冶金、化工、环保、医药等部门得到了广泛的应用,已成为目前分析实验室中最有用和最基本的分析手段之一。原子吸收光谱仪基本上由三部分组成:光源、原子化器和检测读出系统。原子吸收的光源要求能发射被测元素的特征辐射(共振线),通常取用空心阴极灯。原子化器把样品中的被测元素变成原子蒸
Atomic absorption spectroscopy is a new analytical method developed since the 1950s. This method of high sensitivity, good selectivity, easy to operate, the application of a wide range. In the metallurgical, chemical, environmental protection, medicine and other departments have been widely used, has become the analysis of the most useful laboratory and one of the most basic analytical tools. Atomic absorption spectrometer basically consists of three parts: light source, atomizer and detection readout system. Atomic absorption of the light source required to emit the characteristics of the measured element radiation (resonance line), usually using hollow cathode lamp. The atomizer turns the element under test into an atomic vapor
