Abstract: The effects of (a) flow-rate,(b) tube length,(c) tube inner diameter, (d) sample volume injected and (e) temp. on dispersion in an air-segmented flow injection system were studied and the performance of instrument was examined by using sample solution of iron(Ⅲ)sulfosalicylate. The results indicate that dispersion of sample plug is only dependent on sample volume and flow-rate. Tube length and diameter, temperature have only slight effect on the dispersion. So the proposed method was very suitable for the slow reaction systems and reactions need heating.

Key words: Air-segmented flow injection analysis, Degree of dispersion, Fe
