These hydrophilic polymers are suitable for both aqueous SEC and organic GPC using the majority of polar organic solvents. Polyethylene oxide (PEO) kits are available in high molecular weights, while the Polyethylene glycol (PEG) kits 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. Every kit contains 0.2 g or 0.5 g of ten different molecular weight standards.
Polyethylene glycol is now available in the time saving and easy to use EasiVial
format, a combined PEG/PEO is also available.
