FAQs

Question: What nominal molecular weight is supplied?

Answer:20,000 Da peak molecular weight (Mp).

Question: Is this a ready-to-inject PEG calibration mixture?

Answer:No. It is an individual 1 g polymer standard requiring suitable preparation.

Question: How does it differ from the 13,000 Da PEG grade?

Answer:It provides a higher nominal Mp reference for the same calibration family.

Application Note

The Agilent Polyethylene Glycol GPC/SEC Standard with nominal Mp 20,000 Da is a 1 g individual reference material used in polymer size-exclusion chromatography. Polyethylene glycol is a neutral, water-soluble polymer that can serve as a calibration reference in aqueous and selected polar solvent systems. Its 20,000 Da peak molecular-weight designation places it above the 13,000 Da PEG standard in a multilevel calibration, helping cover a broader molecular-size interval. A useful calibration curve requires multiple appropriately spaced reference materials, consistent eluent composition and stable column temperature. Prepare this standard at a concentration that avoids overloading the SEC packing and inject under reproducible conditions. Retention times depend on column pore architecture and solvent interactions, so transferring a PEG calibration between columns must be evaluated. This product is an individual polymer powder, not a premixed multicomponent calibration kit or a certified solution. Use lot-specific characterization data when interpreting molecular-weight distributions.
