目前,各单位使用的分光光度分析仪器多数是:苏联的CΦ-4型石英分光光度计、英国的Unicam SP-500型分光光度计和民主德国蔡司厂出品的通用分光光度计等数种。前面二种仪器,由于把主要的元件几乎都固定在一个壳体上,故供校正及实际操作的旋钮、开关等就比较少,工作起来颇为方便。后一种仪器,由于它的高度灵活性及多用性,整套仪器由电压稳定器、光源、单色器、接收器、示零器(静电计)、补偿器等几个主要的独立元件组成。这些元件,除了用作分光光度
At present, most of the spectrophotometric instruments used by each unit are: the CΦ-4 type quartz spectrophotometer in the United States, the Unicam SP-500 spectrophotometer in the United Kingdom and the universal spectrophotometer manufactured by the German company Zeiss in Germany. The first two kinds of instruments, as the main components are almost always fixed in a shell, so for the correction and the actual operation of the knob, switch, etc. is less, it is quite convenient to work. The latter instrument, due to its high degree of flexibility and versatility, consists of several major independent components such as voltage stabilizers, light sources, monochromators, receivers, indicating devices (electrometers) and compensators. These elements, except for spectrophotometry
