Sample: water soluble polymer

Question
Equivalent to Waters Ultragel 120 and 250, separate analyte w MW 1500 & 6950, but also need to check other compounds maybe in the MW range of 1000-~20,000

Answer
The direct equivalent of Waters Ultragel 120 and 250 would be SB-802 and 803.If the analyte behaves like pullulan, I think SB-803 by itself should be able to separate analytes with MW ~1500 and ~7000 (and unless they have very large MW distributions).
