Claim 0:
1. An automatic sample injection device comprising:
an injector configured to perform a sample injection operation to an analysis device, the sample injection operation including a plurality of steps; and
a management device configured to perform operation management of the injector,
wherein the injector includes:
a turret configured so that a plurality of vials are loaded at preset locations on the turret, wherein the vials are used in the sample injection operation and types of the vials are distinguished by composition or application of liquid to be accommodated therein; and
a vial sensor configured to detect whether or not a vial of the plurality of vials has been loaded at a predetermined location on the turret,
wherein the management device includes a processor configured to:
set a condition relating to a type or types of vials to be used in the sample injection operation, based on information input by a user; and
determine, before the injector initiates the sample injection operation, whether or not there is a missing vial on the turret out of the vials of the type or types set to be used in the sample injection operation under the set condition, by using a detection result of the vial sensor,
wherein the turret is configured so that a plurality of vials of the same type can be loaded on the turret,
wherein the processor is configured to determine whether or not a vial of a type set to be used a plurality of times has been loaded on the turret in a case where the plurality of vials of the same type are set to be used a plurality of times in the sample injection operation,
wherein the processor is further configured to generate sequence information for the sample injection operation based on the set condition, by generating the sequence information by setting the vial to be used in each of a plurality of steps, based on a determination result of the processor indicating whether or not the vial of the type set to be used the plurality of times has been loaded on the turret, and
wherein the injector is configured to perform the sample injection operation based on the sequence information generated by the processor.
