A plate suitable for use with mass spectrometers comprising a number of target spots arranged in a surface portion of said plate making it possible to deposit small amounts of fluid at said target spots without the fluid escaping or getting mixed with fluid deposited at another target surface of the same plate. The target surfaces being arranged in a surface portion of said plate so that a base material of said plate constitutes the walls of receptacles, characterised in that the shape, size, temperature and possible agents of said receptacle facilitate evaporation of a solution in which sample molecules are suspended. Embodiments include different types of matrix and enzymes arranged at said spots, and methods for enhancing MALDI analysis efficiency. |
