Notes:
The matrix-assisted desorption/ionization of large biomolecules with a wavelength of 2.94 μm in the infrared is reported. A mechanically Q-switched Erbium-YAG laser with a pulse width of ca. 200 ns was used for the experiments. A large variety of matrices have been used successfully, among them all matrices found useful for ultraviolet desorption and, in addition, carboxylic acids, glycerol and urea. Desorption of molecules at this wavelength and caffeic acid as a matrix results in ions with up to 13 charges per ion.
