Comparison with ODS Column (2)

The comparison of Asahipak GF-310 HQ (an Aqueous/Organic (multi-solvent use) SEC column) and an ODS column when they were used for the measurement of POE distribution of octylphenol ethoxylate is shown here. Comparing the retention times of peaks, we can say that octylphenol ethoxylate of different degree of POE polymerization can be separated by GF-310 HQ more sufficiently than by an ODS column.


Sample : Octylphenol ethoxylate
