PURPOSE:To increase the speed of analysis and to enhance the reliability of analysis by mounting an optical detection means on the lateral side of a sample container of transparent material quality and obtaining the data of the depth direction of the container to control the penetrating depth of a probe into the sample container. CONSTITUTION:A sample container 2 is set at a sample sucking position by rotating a turntable 20 and an optical detection means 10 is provided on the lateral side of the container 2 at the sample sucking position and the range larger than the total length of the container 2 is measured with respect to the depth direction of the container 2. That is, the container 2 is irradiated with light from the detection means 10 and the data of the depth direction in the container 2 can be obtained from the intensity of the reflected light from the container 2. A probe 4 sucking a sample to emit the same to a reaction tube is mounted on the leading end part of an arm 6 above the container 2 at the sample sucking position and the arm 6 is moved in a vertical direction and the rotary direction within a horizontal plane by an arm driving means 8. A control means 22 inputs the signal from the detection means 10 and obtains the data of the depth direction in the container 2 from the detection signal of the detection means to control the arm driving means 8. By this method, the reliability of analysis can be enhanced. |
