tailieunhanh - Characterization of complex polyether polyols using comprehensive two-dimensional liquid chromatography hyphenated to high-resolution mass spectrometry

Polyetherpolyols are oftenusedinformulatedsystems,buttheir complete characterizationis challenging, because of simultaneous heterogeneities in chemical composition, molecular weight and functionality. One-dimensional liquid chromatography–mass spectrometry is commonly used to characterize polyether polyols. |
