- An example of the exhaust means 305 is a vacuum pump or the like whose operation can be controlled by an analyzer. Further, a valve 306 may be provided between the opening of the exhaust means 305 and the drain.
- the first example is a method of moving the evaporation concentration mechanism 131.
- the control unit 104 moves the evaporation / concentration mechanism 131 so that the point at which the transfer mechanism 132 accesses the evaporation / concentration mechanism 131 coincides with the container receiving unit 301.
- the reaction vessel 116 is transported to the container receiving unit 301 on the standby unit 303 by the transport mechanism 132, and after waiting for a certain period of time, the purified liquid is used. Is introduced into the separation unit 102 by the dispensing mechanism 133 for the separation unit.

Assuming that the throughput is 100 samples / hour (36 seconds / sample) and the time required for evaporation concentration is 108 seconds (36 seconds x 3), the evaporation concentration unit 302 and the standby unit 303 each have three container receiving units. If 301 is provided, the evaporation concentration mechanism 131 can sequentially process the reaction vessel 116 without any free time even when the same treatment is continuously carried out, and a throughput of 100 samples / hour can be obtained. At this time, the exhaust means 305 is required for each of the three container receiving portions 301 in the evaporation concentrating portion 302.

Then, in the separation unit 102, the separated components are moved to the analysis unit 103, and analysis is performed.
- an automatic analyzer capable of controlling the evaporation concentration of the sample by selecting whether or not the evaporation concentration is performed for each sample.
