Separation using planar chromatography with electroosmotic flow.
Planar chromatography with electroosmotic flow is used to separate either a mixture of dyes using 80% aqueous ethanol as the mobile phase or a mixture of miscellaneous compounds using 45% aqueous acetonitrile as the mobile phase. Both mobile phases are 1.0 mM in N-[tris(hydroxymethyl)methyl]-3-aminopropanesulfonic acid (TAPS) buffer. Separations using this technique are faster and more efficient than the same separations by conventional TLC. The respective relationships between migration velocity and applied potential, and between analysis time and distance migrated, are presented.
