Polyethylene Glycol, Polyethylene Oxide Standards
These hydrophilic polymers are suitable for both aqueous and organic GPC/SEC using most polar organic solvents. The polyethylene oxides (PEO) are available in high molecular weights, while the polyethylene glycols (PEG) cover the lower molecular weight range. The two types are chemically similar so they can be used together across a wider molecular weight range, with individual molecular weight aqueous and organic polymer standards from 62 to 1,300,000 Da.
