摘要：

Ethoxylated fatty alcohols can be characterized by two-dimensional chromatography with LC under critical conditions as the first and size-exclusion chromatography (SEC) as the second dimension. The dependence of response factors on the chemical composition can be compensated by two different approaches. The results obtained are in good agreement. The SEC calibrations for the individual homologous series showed considerable differences, hence for each fraction the corresponding calibration should be used.
