For measurement of molecular weight distribution by SEC mode, it is necessary that no interaction exists between packing material and the sample. Therefore it is important the eluent in which any interaction does not exist between packing material and sample, is selected. Considering the properties of the polymer such as hydrophobicity, hydrophilicity, ionic, nonionic as well as eluent can aid in the column selection.
