Polyethylene Glycol (PEG)/Polyethylene Oxide (PEO) Individual Standards
These hydrophilic polymers are suitable for both aqueous SEC and organic GPC using the majority of 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 aqueous and organic polymers from 106-1 million MW. Polyethylene glycol is now available in the time saving and easy to use format A combined PEG/PEO is also available.
