摘要:

以大型仪器原子吸收光谱仪、电感耦合等离子体发射光谱仪为例,说明当沙尘天气发生时,空气中的粉尘和微小颗粒进入到仪器内部会引起空气压缩机故障、射频发生器的传感器不工作、助燃气堵塞等一系列问题;并针对这些问题进行处理,给以后仪器的使用和保养提供相应的参考。

Abstract:

The frequent occurring sandstorms have a great impact not only on people's daily life in the northern region, but also on the routine working of the sophisticated instruments. In this paper, a summary was provided about the operation performance of the instrument in the circumstance of the dust weather. For the atomic absorption spectrometer (AAS) and inductively coupled plasma atomic emission spectrometer (ICP-AES), the entering of dusts in the interior of the instrument would cause the fault of the air compressor and the radiofrequency (RF) generator sensor, as well as the block of the pipes of the assistant gas. This paper provides solutions to these problems and suggestions are made for instrumental operation and maintenance.

Key words: Dust, Sandstorm, AAS, ICP-AES
