Alcohol ethoxylates (AEs) are nonionic surfactants. They are industrially important compounds that have historically been difficult to analyze, with the best results to date achieved through derivatization (e.g., silylation) followed by analysis by gas chromatography/mass spectrometry (GC/MS). Recen
## Abstract A comprehensive twoβdimensional liquid chromatography system was developed to precisely describe the molecular heterogeneity of fatty alcohol ethoxylates. The endβgroup functionality was analyzed by gradient HPLC while ethylene oxide oligomer distributions were characterized by liquid a
