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
