The objective of this research was to connect FIA using developed instrument NAG-4SX3-3D analyzer with AFM to explain the surface morphology. Based on the reaction of Fe (II) ion with [Fe(CN)6]3-, in order to form a blue precipitate, a steady feed was used to achieve an appropriate amount of weight for the AFM study. In relation to the type of precipitate formed, different factors of AFM photograph surface roughness analysis were referenced to clarify the study of surface topography: Skewness, Kurtosis, peak-peak, ten peak height, wave length, fractal dimension, reduced valley depth and core roughness depth, all of which, primarily dealt with the four parameters hybrid, spatial, amplitude and functional. Since no prior study of such has been conducted, all common modes of imaging have been discussed, i.e., contact, non-contact and Occasional contact was defined. In this work, a non-contact mode was used. A comprehensive investigation was done about how the first mono layer is built up by crystallization process and also, how much each grain represent a concentration with the number on the first mono layer. The number of surface area calculation samples was given plus a demonstration of the multi monolayer hypothetically formed especially at high reactant concentration. The primary purpose of the project was to connect AFM to FIA, which is seen as a modern method that could be a very valuable interpretation for other researchers. This gives this research a novelty as no previous study has addressed it. As most FIA method emphasis on the method by developing any methodology for determination of ionic species without regarding the surface morphology of the precipitated molecular ion followed by the formation of nuclei, small particulate then finally forms granules which was studied by SPM.
