Abstract: A moving mechanism and a spray mechanism are controlled to spray a reagent from a nozzle to a sample plate while relatively moving the sample plate and the nozzle. The reagent is applied to an entire application area by moving a spray spot of the reagent sprayed from the nozzle, on the sample plate from a start point to an end point. At this time, the spray spot is moved in a sample placement area after a spray amount of the reagent from the nozzle and a moving speed of the spray spot become constant.
