Popis:	A method for systematic analysis of esters of nonionic surfactants was carried out.When the UV/RI ratio were plotted against the elution volume for Tween type and Span type surfactants, relationship between the UV/RI ratio and elution volume was displayed specific pattern to each surfactants.When nonionic surfactants were analyzed with methanol-tetrahydrofuran (1:9) as a mobile phase on the Gel Permeation Chromatography, systematic analysis of two esters of nonionic surfactants were quantitatively enabled.By the use of calibration curves of standard polystyrene were known to be measurable the molecular weight Tween type and Span type surfactants.
