Abstract

The present disclosure is directed to surface modified materials such as stationary phase materials for performing size exclusion chromatography. Aspects of the present disclosure feature materials surface modified with a moiety including a polyethylene glycol (PEG) functionality and a moiety comprising a diol functionality. Such surface modified materials exhibit a reduced propensity for ionic and hydrophobic secondary interactions.
