A serpentine electrophoresis channel, e.g., for a microchip format, is disclosed. The channel includes pairs of linear segments, e.g., parallel or right-angle segments, each joined by an angled channel region having a first curved channel portion subtending an angle alphaf>alpha, where alpha is the angle between segments in a pair, and a second curved channel portion subtending an angle alphas=alphaf-alpha. The angles and cross-sections of the two channel portions are such that deltatf, the time differential of analyte migration at inner and outer tracks in the first curved portion is equal to deltats, the time differential of analyte migration at outer and inner tracks in the second curved portion, respectively. |
