A new method of liquid sample introduction for a time-of-flight mass spectrometer (TOF-MS) has been developed by applying the method of matrix-assisted laser desorption ionization to aerosols. Analyte biomolecules are dissolved in a methanol solvent along with a UVabsorbing matrix and formed into an

β¦ Synopsis
Most characteristics of matrix-assisted laser desorption/ionization (MALDI) are ideal for the analysis of biomolecules. New preparation techniques have dramatically increased mass accuracy and resolution, making MALDI a high-performance mass spectrometric technique for peptide mass analysis. Attempts to obtain amino acid sequence information by MALDI have been partially successful. The technique has been put to novel uses in protein primary structure characterization.
