故障现象:一台刚买的XGY—1012型原子荧光光度计使用半年后出现灵敏度低,荧光强度响应值小的故障。原因分析:该机由气体流动注射氢化物气体发生器,低温点火石英炉原子化器、激发光源,光电转化器。检测显示系统、计算机数据处理系统组成。如图1所示。
Symptoms: A newly purchased XGY-1012 atomic fluorescence spectrophotometer using six months after the emergence of low sensitivity, fluorescence intensity response small fault. Analysis: The machine consists of gas flow injection hydride gas generator, low temperature ignition quartz furnace atomizer, excitation light source, photoelectric converter. Test display system, computer data processing system. As shown in Figure 1.
