Development of planner open channel ion chromatography and application to multiple atmospheric gas analysis

In this study, planner open channel separation column for ion chromatography has been investigated. The channel was large aspect ratio which made larger surface area for interaction and smaller diffusion distance. Also, this made smaller pressure drop. One of the merit of planner column was ease of changing solid phase. The solid phases were prepared batchwisely with polystylene, and glass substrates. Prepared column showed separation phenomena. However, separation factor was not enough for practical usage. Also, ion transfer method for sample introduction was investigated. Ions were transferred from sample to accepter solution under the electrical field quantitatively.
