JEOL USA demonstrates gas chromatography-time-of-flight mass spectrometry (GC-TOFMS) and matrix-assisted laser desorption/ionization (MALDI)-TOFMS approaches for analyzing polymeric materials.
These approaches are shown alongside the composition analysis of ultraviolet (UV)-curable resins, monitoring analysis of epoxy curing, and further examples. In the webinar section describing the compositional analysis of UV-curable resin, the significance of separation for MS analysis is discussed.
Monomer, photo-initiator, reactive oligomer, and polymer structures were challenging to determine through bulk analysis and clearly distinguished via gel permeation chromatography fractionation.
The effectiveness of a Kendrick Mass Defect (KMD) plot will be discussed in the section discussing tracking analysis of epoxy curing. KMD plots are generally utilized to analyze polymer terminal groups.
JEOL USA sought to investigate the epoxy curing’s mechanism. Stemming from this, it was possible to visualize reaction behavior at the first stage of the reaction.
