The polystyrene oligomers’ separation performance of GPC FP-2002, a column for organic SEC (GPC), is compared with that of other manufacturer’s rapid separation columns (molecular weight exclusion limits (ML):5,000 and 1,000). Even FP-2002 has higher exclusion limit than the competitor’s column, it has superior separation in the low molecular weight range.
