title: [Development and evaluation of a system for pulse generation and signal processing control in a plasma atomic fluorescence spectrometer with hollow cathode lamp as excitation source].
abstract: A Z80 processor was replaced with a 386 microcomputer to control pulse generation for hollow cathode lamp and fluorescence signal processing in a Baird Plasma AFS-2000 atomic fluorescence spectrometer. An interface board was designed for control purpose. The system was evaluated with detection limits, relative standard deviations and linear regression coefficients of 15 elements, which were in good agreement with the corresponding values in the manufacturer's manual. With the higher-level microprocessor in the system, the performance of the instrument was improved.
