Abstract:Oscillographic flow injection analysis (dynamic oscillographic analysis)means the combination of flow injection technique with oscillographic analysis and oscillographic determination is carried out in continuously flowing solution. Flow-through cell which suited to oscillographic analysis is designed. New technique with feedback voltage is first presented. Reproducibility, detection limit and influences of different factors on peak height of depolarizer are investigated. The method has the characteristics of easy operation, quick analysis, good reproducibility, high sensitivity, saving reagents, and the difficult problems of static oscillographic method have been solved. Therefore, oscillographic determination methods will become a series of really feasible analytical methods.
Keywords:Dynamic oscillographic analysis  Flow-through cell  Voltage feedback  Flow in-jection
