【Abstract】 Genetic algorithm (GA) is used in automatic qualitative analysis by a sequential inductively coupled plasma spectrometer (ICP AES) and a computer program is developed in this paper.No any standard samples are needed,and spectroscopic inteferences can be eliminated.All elements and their concentration ranges of an unknown sample can be reported.The replication rate P r ,crossover rate P c and mutation rate of the genetic algorithm were adjusted to be 0 6,0 4 and 0 respectively.The analytical results of GA are in good agreement with the reference values.It indicates that,combined with the intensity information,the GA can be applied to spectroscopic qualitative analysis and expected to become an effective method in qualitative analysis in ICP AES after further work.更多还原
