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, each of those moieties at a coverage density of at least 0.05 μmol/m2. Such surface modified materials exhibit a reduced propensity for ionic and hydrophobic secondary interactions.

Abstract: The present disclosure relates to a system for separating a sample including a device and a positive pressure source. The device can include a housing with a proximal end having an interface and a proximal end opening, a distal end opening opposite the proximal end opening, and an interior wall defining an interior of the housing; a bottom frit connected to the interior wall, extending across the interior of the housing, and located proximately to the distal end to minimize sample loss; and a resin disposed within the interior of the housing between the bottom frit and the proximal end. The positive pressure source can connect to the interface of the proximal end to apply positive pressure to the sample. A controller can control the applied positive pressure to the sample via the positive pressure source according to a relationship between the bottom frit, the resin, and the positive pressure.
