Abstract
Protected deoxyribonucleotides were identified by field desorption mass spectrometry in eluate fractions from high performance liquid chromatography. The production of abundant cationized molecules and the formation of structural significant fragments by thermally/field induced processes allowed a direct and unambiguous identification of the synthesized products. In addition, indications can be obtained on both organic and inorganic impurities.
