    摘要: A method for separating a sample comprising a plurality of compounds includes loading a sample onto a planar stationary phase, said sample comprising a plurality of compounds to be separated; and, while retaining the sample on the planar stationary phase, subjecting the sample to planar electrochromatographic separation in a selected direction using a first mobile phase; and subjecting the sample to a chromatographically-based separation in a direction other than that of the direction used for planar electrochromatographic separation using a second mobile phase. Separation is optionally followed by direct detection of analytes using mass spectrometry (MS). These three dimensions of separation are orthogonal to one another, providing for improved resolution of the analytes.
