GPC calibration PEGs

The quality of the PEG analytical standards is very important for GPC characterization of PEGs and PEGylated products. JenKem Technology’s PEG GPC calibration standards have narrower polydispersity and more accurate molecular weights compared to other PEG standards on the market.  The molecular weights of JenKem PEG standards are determined by MALDI-TOF. The polydispersity of JenKem PEG standards is determined by GPC. JenKem 4armPEG Standards

Gel permeation chromatography (GPC) is a type of size exclusion chromatography. GPC separates mixture components based on molecule size, and it can be used to determine the number average molecular weight (Mn), weight average molecular weight (Mw), and peak average molecular weight of polymers.
