MALDI-CID Study of Poly(methyl methacrylate)

Surface Layer MALDI-MSI of Synthetic Materials on a Molecular Level A surface-layer matrix-assisted laser desorption ionization mass spectrometry imaging technique (SL-MALDI-MSI) is developed to study the chemical composition of multicomponent polymer surfaces. Abstract Using this technique, four different types of…

Polystyrene analysis using MALDI-TOF MS Three polystyrene samples covering a mass range from 2 kDa to 200 kDa were analyzed using an autoflex maX MALDI-TOF MS. Abstract For all samples, several characteristic values were determined, including the average molecular weights…

POLYMER ANALYSIS APPLICATIONS [ POLYMER ANALYSIS APPLICATIONS ] ADVANCING POLYMER SCIENCE INTRODUCTION Today’s polymer manufacturers operate within an increasingly dynamic market space that is fueled by intense competition, complex regulatory considerations, and a true resurgence in polymer development spurred by…

MASS SPECTROMETRY FOR POLYMERS Benefits and analytical considerations for MS analysis of polymers The benefit of mass spectrometry is the ability to make absolute mass measurements at a molecular level rather than an average across a whole sample, making mixtures…
