This paper describes implementation of instrument control and data analysis software for fully automated, unattended analysis of metals by flame atomic absorption spectrometry (FAAS). Error trapping and correction are an essential part of the software system if an automated instrument is to run unattended. The design and implementation of two programs, AA-Quality Control (AA-QC) and AAcontrol, that form part of the expert system AAexpert are described. AAcontrol carries out instrument control, automated sample handling, and data measurement by FAAS. AA-QC uses the time profile of the absorption of the metal atoms in the flame following aspiration of small volumes of samples to recognize in real-time the failure of data values to meet quality control standards. A series of criteria are applied to the absorption profile to aid in diagnosis of problems that arise during solution transport. AA-QC is a

Expert system technology is an essential new tool for the analytical chemist. In the future, expert systems will play an important role in developing new methods and procedures, in enhancing productivity,
