Beschreibung
Zusammenfassung:	The present disclosure relates to stationary phase materials for size exclusion chromatography. Embodiments of the present disclosure feature a hydroxyl-terminated polyethylene glycol surface-modified silica particle stationary phase material, which is optionally also surface-modified by methoxy-terminated polyethylene glycol. 本公开涉及用于进行尺寸排阻色谱法的固定相材料。本公开的实施方案的特征在于羟基封端的聚乙二醇表面改性的二氧化硅颗粒固定相材料，该二氧化硅颗粒固定相材料任选地也是甲氧基封端的聚乙二醇表面改性的。
