Shear-Driven Flow Ice Chromatography as a Possible Tool Probing Ice/Water Interface

Abstract

Although ice chromatography is a useful probe of ice interfaces, its low separation efficiency has often made difficult to access the ice/water interface. Coupling of this method with shear-driven flow chromatography, which has high separation potential, solves the problems involved in ice chromatography. This paper reports on shear-driven flow ice chromatographic instrumentation, and discusses the separation performance. Electrostatic separation of positively and negatively charged dyes is demonstrated with an OH⁻-doped ice plate as a stationary phase.
