Paper Abstract

A two-step laser vaporization/laser multiphoton ionization method is used to analyze and detect polymers. In this method a pulsed CO2 laser is used to vaporize the polymer for supersonic jet entrainment and then a second (UV) laser ionizes the desorbed species. The resulting ions are analyzed in a reflection time-of-flight (TOF) mass spectrometer. The challenges here include selectively detecting an aromatic polymer in a polymer blend and studying molecular weight distributions.
