eng	Analysis of Surfactants by Combination of HPLC and CZE	In this work, automated off-line two-dimensional LC-CZE method previously developed in our laboratory was applied for the analysis of NPE samples with the aim to separate them also according to the nonyl- chain isomers. In the first RP-HPLC dimension the different columns were tested to obtain the best separation of oligomers of NPEs. In the second CZE dimension both uncoated and coated capillaries, different buffer composition and addition of different types of cyclodextrins as isomer selectors were investigated to resolve the possible branch isomers of nonylphenol group.	Surfactants; 2D LC-CZE
