Abstract

The retention of tributylphenol-ethylene oxide oligomer surfactants was determined in reversed-phase high-performance liquid chromatography using various supports (C1, C2, C6, C8, C18, polyethylene-coated silica, polyethylene-coated alumina and alumina-based C18). The retention data matrix was evaluated by spectral mapping followed by non-linear mapping and cluster analysis. The retention capacity of polyethylene-coated silica and alumina as well as C1 column was similar. Surfactants formed distinct clusters on the two-dimensional non-linear map of the spectral map according to the length of the ethylene oxide chain. Significant linear correlation was found between the carbon loading and the retention capacity of columns, indicating the preponderant role of the quantity of hydrophobic alkyl chains in the determination of retention capacity.
