An automatic analysis apparatus according to the present invention is capable of replacing circulated water in a reaction vessel and continuously cooling a light source lamp without stopping an operation for measuring a specimen. In an operation state, a drain electromagnetic valve 49 is opened, and reaction vessel water 18 is drained outside. When the water level reaches a measurement limit water level 45, the drain electromagnetic valve 49 is closed. The reaction vessel water 18 is supplied by starting a water supply pump and opening a water supply electromagnetic valve 48. When a first water level detector 41 confirms that the water level has reached a full water level 44, the water supply electromagnetic valve 48 is closed, and the water supply pump 54 is stopped. In a state other than the operation state, the reaction vessel water 18 is drained outside. When a third water level detector 43 confirms that the water level has reached a circulation limit water level 46, the drain electromagnetic valve 49 is closed. When the water supply electromagnetic valve 48 is opened and the reaction vessel water 18 reaches the full water level 44, the water supply electromagnetic valve 48 is closed and the water supply is stopped.

The presently disclosed subject matter provides a pattern measurement method and device for achieving highly accurate measurement in the depth direction of a pattern. The method involves a focused ion beam irradiated to form an inclined surface in a sample area; a field of view of a SEM set to include the boundary between the inclined surface and a sample surface; and an image of the field of view obtained on the basis of a detection signal. Such an acquired image is used to specify a first position, the boundary between inclined surface and non-inclined surface, and a second position, the position of a desired deep hole or deep groove positioned within the inclined surface. The pattern dimension in a height direction is determined on the basis of the distance in the sample surface direction between the first position and second position and the angle of the inclined surface.

The present invention provides a liquid stirring method that makes it possible to stir evenly without reducing dispensing and analysis throughput and while avoiding the risk of splashing or bubbling even if the amount of liquid to be mixed within a container is low. In a liquid stirring method according to the present invention, after a second liquid is discharged into a reaction container (4) accommodating a first liquid from a dispensing probe (1) provided with a dispensing tip (3) at the leading end thereof, a mixture of the first liquid and second liquid in the container (4) is stirred by being sucked out and discharged by the dispensing probe (1). The number of stirrings through sucking out and discharging is changed according to the total volume of the first liquid and second liquid. If the total volume of the first liquid and second liquid is below a preset threshold, sucking out and discharging is repeated for a prescribed number of times.

The present invention achieves an automatic analysis device which has a probe guard for which the range of motion for accessing a specimen container installation section is small and which can be moved without being removed from a specimen installation section. The directions of movement of a probe guard (26) are the vertical direction of a specimen container erection mechanism (1) and the horizontal direction within an upper region of the specimen container erection mechanism (1), and a specimen container can be accessed without the need to move the probe guard (26) to outside the upper region of the specimen container erection mechanism (1). Accordingly, it is possible to achieve an automatic analysis device which has a probe guard (26) for which the range of motion for accessing a specimen installation section is small and which can be moved without being removed from a specimen container erection mechanism (1).
