AN EXPERT-SYSTEM CONTROLLER FOR GAS-CHROMATOGRAPHY AUTOMATION

We report on the development of an expert system to control the use of a gas chromatograph system in the analysis of hazardous wastes. This automation process allows for analyses to be performed in both a more rigorous and systematic manner, and with an increased rate of throughp ut. The system includes techniques to monitor the progress of the anal yses and determine if any problems or unusual circumstances warrant st opping or changing the process. Our system has been both designed and validated with assistance of analytical chemists.
