| Abstract: | The kinetic method, which is known to be simple, fast and precise, is used for the measurement of proton affinity values of fifteen selected matrix-assisted laser desorption/ionization matrices under electrospray ionization conditions. The stabilization of M - H](-)/M + Matrix - H](-) ions for beta-cyclodextrin in negative ion mode has been rationalized based on the proton affinity values of the matrices. |
