1. A method for drawing-off liquid from individual droplets which are in an arrangement on sample spots of a flat substrate and contain sedimented material, the method comprising:
positioning a mask of an absorbent material above the flat substrate, the mask comprising a pattern of indentations or holes that corresponds to the arrangement of the individual droplets in such a way that each sample spot has a respective one of said indentations or holes opposite it; and
lowering the mask so that edges of the indentations or holes come into contact with peripheral parts of the individual droplets such that liquid is drawn off into the absorbent material.
