Abstract
The fluid temperature within piping of a sample dispensing system is stabilized in order to maintain stable dispensing performance with high precision in an automatic analyzer. A controller executes a first operation sequence to operate the sample dispensing system in a standby state continued until the sample is transported to the sample dispensing position, and executes a second operation sequence to operate the sample dispensing system in an analysis state in which the sample located in the sample dispensing position is dispensed. A time period during interior cleaning performed on the sample probe in a single cycle of the first operation sequence is set to be shorter than a time period during interior cleaning performed on the sample probe in a single cycle of the second operation sequence. Alternatively, the first operation sequence is configured to perform interior cleaning at a rate of once every multiple of cycles.
