Agilent Polyethylene Glycol / Oxide (PEG/PEO) Standards
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.
Available as Calibration kit, where each kit contains 0.2 g or 0.5 g of ten different molecular weight standards, or as Individual Polymer Molecular Weights.
Polyethylene glycol is now available in the time saving and easy to use EasiVial format, a combined PEG/PEO is also available.
- Also available in a simple-to-use kit form
- Combines glycols and oxides to extend the MW range and cover more applications
- MWs selected to provide equidistant calibration points for greater accuracy
