WebApr 1, 1998 · 1.3.. Sample PreparationPolymer samples for MALDI analysis were prepared by combining the analyte, matrix and cationizing agent in THF 19, 21. All-trans retinoic acid was prepared to a concentration of 0.15 M. In a typical experiment, polymer stock solutions (1 mM, calculated from the nominal molecular weights) were diluted tenfold with the … WebNov 8, 2024 · Matrix-assisted laser desorption ionization high-resolution time-of-flight mass spectrometry (MALDI HR TOF MS) is a powerful tool for the molecular characterization of industrial polymers. However, accurate mass determination and resolution of isobaric ions are possible for oligomer samples only typically below m/z 3000. To cut long polymer … WebDec 15, 2016 · Here we extended the method to a synthetic organic material using polymer probes characterized by MALDI-TOF/MS. We first characterized several commercial available polymers, and finally selected polycaprolactonediol 1250 (PCP 1250), a polyester oligomer, as the most convenient for further studies. population reduction
