Abstract

MATRIX EFFECTS ARE PROMINENT WHEN USING LIQUID MATRICES FOR MASS SPECTROMETRY. A GOOD UNDERSTANDING OF THESE EFFECTS WILL IMPROVE THE EFFICIENCY OF THE IONISATION-DESORPTION PROCESS. IN THIS REVIEW, THE VARIOUS PHASES OF THE ION EMISSION PROCESS ARE DESCRIBED AND A TENTATIVE MECHANISM PRESENTED THAT COPES WITH ALL THE AVAILABLE RESULTS. THE INTRODUCTION OF LIQUID MATRICES ON LSIMS AND FAB ALLOWED LASTING SIGNALS TO BE OBTAINED FOR FRAGILE MOLECULES WITHOUT APPARENT DAMAGE ACCUMULATION. THE IONISATION PROCESS, DAMAGE PROCESS AND KINETIC AND INTERNAL ENERGY MEASUREMENTS ARE ANALYSED. LSINS AND FAB HAVE BECOME IMPORTANT TOOLS FOR ANALYTICAL OR STRUCTURAL CHEMISTS.
