Analyte molecules partition between a liquid stationary stage plus the eluent. Equally as in hydrophilic interaction chromatography (HILIC; a sub-method within just HPLC), this technique separates analytes based upon differences in their polarity. HILIC most frequently uses a bonded polar stationary section plus a cell phase made generally of aceto
