- ACQUITY APC columns

No, this is not recommended. See additional information below.
ACQUITY APC AQ columns are packed with an unbonded BEH (bridged ethylene hybrid) particle. PEG and PEO can undergo secondary interactions with this packing, so ACQUITY APC AQ columns are not the best choice for analysis of PEG or PEO.
Instead, Waters has found that the ACQUITY UPLC BEH SEC columns (normally used for protein size exclusion chromatography) work very well for PEG and PEO analysis. The packing in these columns is made with the BEH particle bonded with diol groups.
