MS of Polymers/Materials II: HPLC and Ion Mobility Separation

Wednesday afternoon's session titled "MS of Polymers/Materials II: HPLC and Ion Mobility Separation" is part II of Wednesday morning session, "MS of Polymers/Materials I: Structures and Properties." The second half of this session will pick up where part one left off and address additional topics involving HPLC and other applications.

The first presentation in this session will be given by Mark Arnould of Xerox titled, "Polymer Analysis using GPC, Thermospray Deposition and MALDI-ToF Mass Spectrometry," and will begin at 2:30 PM. Arnould is planning to discuss novel Instrumentation and "high-throughput" sample preparation.

The second presentation, scheduled to begin at 2:50PM, will be given by Nilufer Solak and Chrys Wesdemiotis of The University of Akron (Akron, OH). The tallk, "Structural Characterization of a Complex Nonionic Surfactant by LC-MSⁿ" will address the complete structural analysis of a multicomponent industrial surfactant, Tween 85 (polyoxyethylene sorbitan trioleate), by reverse phase LC-MSⁿ.

Following up that presentation is another one at 3:10Pm titled, "Characterization on Poly (n-Butyl Acrylate)s by LC/ESI-MSⁿ," and presented by Junkan Song ¹, Jan W. van Velde¹, Luc L.T. Vertommen¹, Ron M.A. Heeren², and Oscar F. van den Brink¹ of¹Research, Development and Innovation, AkzoNobel and ²FOM Inst. Atomic/Molecular Phy. Their presentation will discuss the structure elucidation of isomers in acrylate polymers and insight in polymerization mechanisms by high accuracy LC/MSⁿ.

"Recent Mass Spectrometric Developments and Investigations for Age Determination of Ball Point Ink Entries on Paper," presented by Dieter Kirsch¹, Vincent Guillou¹, Bernhard Spengler², Peter Seiler¹, and Fritz Koehler¹ of ¹Bundeskriminalamt and ²Analytical Chemistry is next on the agenda. This talk will present two new mass spectrometric approaches for the examination of the authenticity of documents based on different substance classes.

The second to last discussion in this session, "Identification of Poly(p-phenylene terephthalamide) Branching and Metathesis Products," will be given by Anthony P. Gies and David M. Hercules of Vanderbilt University, (Nashville, TN). Their presentation will address a first report of arylamide metathesis reactions, NMP side reactions leading to PPD-T end group modification, and PPD-T branching.

Last, but not least, will be a presentation on "Ion Mobility Spectrometry-Mass Spectrometry of Star-branched poly(ethylene glycols)," byBarbara S. Larsen², Calvin A. Austin¹, Brian Bohrer³, Ellen D. Inutan¹, Sadish Karunaweera¹, David E. Clemmer³, and Sarah Trimpin¹ from ¹Wayne State University (Detroit, MI), ²The DuPont Company, and ³Indiana University (Bloomington, IN). Their presentation will close-out this session with the discussion of IMS-MS cleanly separated star-branched isomeric composition of respective chain lengths variations and from the linear polymer in mixture analysis.
