Application Compendium ANALYSIS OF POLYMERS BY GPC/SEC PHARMACEUTICAL APPLICATIONS Verified for Agilent 1260 Infinity GPC/SEC System This compendium contains Agilent GPC/SEC applications for the analysis of polymers used in the pharmaceutical industry. It covers the analysis of polymers used for binders,...
GPC (gel permeation chromatography) is a powerful technique used for the separation and analysis of polymers based on their molecular size. It is also known as size exclusion chromatography (SEC) or gel filtration chromatography (GFC). In GPC, a porousgel matrix is used as the stationary phase...
The favorable properties of polymers, such as mechanicalstrength, durability, and resistance to chemical and physicaldegradation, coupled with their relative cheapness, meansthat polymers outperform many traditional materials, includingwood and metals, in key applications. With the creation of new ...
GPC/MALDI TOF ANALYSIS OF POLYMERIC COMPOUNDSA method for the analysis of polymers is described, which couples Gel Permeation Chromatography(GPC) with Matrix Assisted Laser DesorptionIonization (MALDI) Mass Spectrometry by means of an automated eluent collection/deposition module designed specifically for ...
