ASMS 2023: A Look at the Monday Morning Oral Session on Polymers

From 8:30–10:30 am, there was an oral session titled, “Polymers,” which took place in General Assembly B. The session, chaired and presided by Anthony Gies of Dow Chemical, included six talks about the application of mass spectrometry in polymer analysis.

At 8:30 am, Chrys Wesdemiotis of the University of Akron in Akron, Ohio, kicked off the session with a talk about the characterization of macrocyclic and ring architectures by collision induced unfolding.

Next, at 8:50 am, Laurence Charles of Aix-Marseille University, discussed how to assess degradability of poly(lactic-co-Glycolic Acid) chains using reactive desorption electrospray ionization mass spectrometry.

Following up on this discussion, at 9:10 am, was Scott M. Grayson of Tulane University. He delivered a talk about using tandem mass spectrometry of dendrimers, hyperbranched polymers, and linear polymers of bis-MPA.

Then, at 9:30 am, Michelle L. Piotrowski of Bausch+Lomb in Rochester, New York, talked about characterizing modified hyaluronic acid materials and their interactions with contact lenses.

In the fifth talk of the session, at 9:50 am, Mark A. Arnould of Bruker Scientific in Billerica, Massachusetts, discussed using LDI-TOF-MS and graphical data analysis of mesophase pitch samples used in carbon fiber production.

To conclude this oral session, Bayan Almasri of the University of Lille talked about the structural identification of polyethylene terephthalate (PET) insoluble polyester polymers and microplastics by chemical depolymerization and advanced mass spectrometry.
