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 ...
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 ...
The main advantage of DRI detectors is that they are universal. This means that they can be used for almost any polymers and any solvents, therefore, their range of possible applications depends only on the user’s knowledge and on whichever practical constraints exist related...
