PEG quantification and examination of molecular weight
2008年11月6日 · The goal of the present study was gravimetric estimation of amounts of different molecular weight (MW) PEG in the cell walls by selective extraction of PEG from cell lumens. Toluene was selected as a solvent with negligible swelling ability for wood, yet capable of dissolving PEG from the cell lumens.
Determination of the molecular weight of poly(ethylene glycol) in ...
2013年2月21日 · A straightforward strategy utilizing liquid chromatography–mass spectrometry (LC–MS) to characterize high-molecular weight PEG in biologic matrices without a need for complex sample preparation is presented. The method is capable of determining whether high-MW PEG is cleaved in vivo to lower-molecular weight PEG species.
