摘要： A samples stage (2) on which a sample (4) is placed can reciprocally move along a guide (5) by a driving mechanism. An image taken by an imaging unit (7) when the sample stage (2) is at an observation position (A) is processed by an image processor (34) and is displayed on a window of a display unit (38). When an analysis operator specifies a measurement area by an operation unit (37), a controller (3) moves, through a stage driver (33), the stage (2) to a sample operation position (B) and a matrix is applied to the specified measurement area by an ejector (9). After that, the stage (2) is moved to an analysis position (C) and a laser light is delivered onto the measurement area on the sample (4) to which the matrix was applied, and the ionization by the MALDI method is performed. This eliminates the need to take out the sample from the apparatus to apply the matrix after the measurement point or measurement area is determined based on a microscopic observation of the sample. Accordingly, the efficiency of the measurement can be increased, and since no positional error of the sample occurs, it is possible to perform an imaging mass analysis for a measurement area of interest with high positional accuracy.
