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 β-cyclodextrin in negative ion mode has been rationalized based on the proton affinity values of the matrices.
