Classification: CPC G | IPC G

Claim 0:
1. An automated analysis device comprising:
a bottle containing a first liquid;
a syringe;
a first flow path, through which the first liquid flows, connecting the bottle with the syringe;
a detector which detects bubbles included in the first liquid in the first flow path;
a tank coupled to the syringe via a second flow path through which the first liquid flows;
a controller coupled to the detector and the syringe, the controller configured to:
operate the syringe to perform a first liquid supply operation,
determine whether bubbles are included in the first liquid,
in response to determining that bubbles are included in the first liquid:
determine a speed of operation of the syringe,
determine a threshold time based on the determined speed of the operation of the syringe,
determine whether a time during which the bubbles are detected by the detector is less than the determined threshold time,
upon determining the time during which the bubbles are detected by the detector is less than the determined threshold time, determine a size of the bubbles to be normal,
upon determining the time during which the bubbles are detected by the detector is greater than or equal to the determined threshold time, determine that the size of the bubbles is abnormal, and
control at least the operation of the syringe based on whether the size of the bubbles is normal or abnormal.
