Matrices for ultraviolet matrix-assisted laser desorption/ionisation mass spectrometry consisting of a salt of an amine reacting as a proton acceptor and an organic substance reacting as a proton donor, wherein either the amine or the organic substance absorbs UV light, are provided These matrices are characterised in that the matrices are in the form of an ionic liquid at room temperature, that the amine is selected from the group consisting of 3-aminoquinoline, pyridine, a primary amine, to whose N atom may be bound a phenyl residue or a linear or branched, saturated C<SUB>1</SUB>-C<SUB>11 </SUB>alkyl residue, which may be substituted with an OH group, a secondary and tertiary amine, to whose N atom may be bound two or three residues, which may be the same or different. With these liquid matrices, error-free and reproducible analytical values can be obtained, and in particular the coupling of the pure mass spectrometric analysis with the additional findings from enzymatic reactions/modifications with the possibility of monitoring is possible. |
