SURFACE COATING FOR LASER DESORPTION IONIZATION MASS SPECTROMETRY OF MOLECULES

摘要

The present invention refers to a process for laser desorption ionization mass spectrometry using a polymer of aniline or an aniline derivative, or phenyl acrylate or a phenyl acrylate derivative. The polymer is a UV absorbing polymer onto which polymer a sample probe can be deposited. With the use of a UV laser beam, the sample molecules can be desorbed and ionized. The addition of a UV absorbing matrix material may not be necessary any more.
