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 EasiVial format, a combined PEG/PEO is also available.

The EasiCal system for organic solvents consists of two different combs, each with ten detachable spatulas supporting a mixture of five polymer standards. The thin film of polymer (approximately 5 mg) on the tip of the PTFE spatulas rapidly dissolves when immersed in eluent to provide two GPC/SEC calibration solutions. A single pack provides ten spatulas of each type, with MWs selected to provide equidistant calibration points for greater accuracy.
