Abstract
In a flow injection analysis method of injecting a predetermined amount of a sample into a continuous flow of a carrier solution and introducing a reaction zone of the sample and the carrier solution into a flow cell, signals representative of the respective absorptions of the reaction zone for a plurality of wavelengths are produced when the reaction zone is passing through the flow cell. The signals are subjected to an at least two-wavelength processing or differentiation processing, thereby providing a desired absorbance of a substance of interest for analysis free of the influence of a ghost component.
