Summary:
Polymeric materials are ubiquitous in our modern society covering a broad range of applications in industries such as automobiles, packaging, medical, and pharmaceutical, to name a few. This increasing complexity in applications has driven the need to produce highly complex polymeric materials. Full characterization of a sample has become a vital part of the development process. Although the usual techniques of characterization such as NMR and GPC provide a lot of information, mass spectrometry (MS) is increasingly becoming a must for polymer characterization.

In this on-demand webinar, learn about the advantages and limitations of single-stage (HR) MS for the determination of the absolute average molecular masses and the nature of chain ends. See how tandem MS, i.e. collision-induced dissociation experiments, can help differentiate isomers and in some cases quantify mixtures of isomers.

Finally, we discuss the use ion mobility, an emerging MS technique. All of these modern MS-based techniques will be illustrated by concrete examples from the laboratory to emphasize the interest of MS in the context of polymer characterization. Hosted by C&EN.
