Abstract

A more comprehensive analysis of symptom of troubles in AFS-2202E doublechannel atomic fluorescence spectrometer and the causes of the failures were described in this paper. Some trouble diagnosis and troubleshooting methods for instrument sensitivity decline, background value increase, communication failure and the troubles in hollow cathode lamp supply, negative high voltage circuit, photomultiplier tube circuit, gas channel, injection system and atomization system were also described in details.
