- it includes pressure fluctuations due to light contact of the sample dispensing nozzle 116a with the bottom of the microcup 110c, and can be configured with determination reference data on the premise of light contact.
- the sample container type determination unit 303 acquires information on the sample container 110 to be dispensed (step S1).
- This step S ⁇ b>1 corresponds to an acquisition step of acquiring information on the sample container 110 .

- a plurality of determination reference data used for determination are stored for each type of sample container 110, and the abnormality determination unit 305A determines whether or not there is an abnormality in sample dispensing based on the determination result of the sample container bottom contact presence/absence determination unit 501. By determining , it is possible to perform abnormality determination using more suitable determination reference data, obtain a highly reliable determination result, and reduce the dead volume amount.
- the abnormality determination unit 305B also determines whether or not there is an abnormality in the dispensing of the sample based on the determination result of the sample liquid volume calculation unit 701 as well. For example, processing that uses determination criteria data classified by liquid volume and container type, processing that estimates the timing at which contact is assumed from the determined liquid volume and container type, and processing that invalidates pressure data after that timing, etc. can be
