## Abstract Four 2,3βdidehydro amino acids were investigated by fast ion bombardment (FIB) and ammonia chemical ionization (NH~3~βCI) mass Spectrometry. The protonated molecules formed by the two techniques were mass selected and their respective collisionβinduced dissociations (CIDs) in the transl

The thermally induced formation of methyl-and phenylthiohydantoin amino acid derivatives from the corresponding N-methyl-and N-phenylthiourea derivatives of amino acids and peptides has been shown to occur in the mass spectrometer. A comparison of the mass spectra of a number of amino acid thiourea
## Abstract Ionic liquids are interesting solvents for a number of applications in chemistry and biotechnology. We characterized five different ionic liquids by laser desorption/ionization (LDI) and by matrixβassisted laser desorption/ionization (MALDI) mass spectrometry (MS) and studied the analys
