Claim 0:
1. A test method that evaluates a surface state of a dispensing probe provided in a dispensing apparatus that dispenses a liquid sample, the method comprising:
a first dispensing step of causing a first dispensing probe provided in the dispensing apparatus to dispense a first solution in which a coloring matter is dissolved to a first container;
a second dispensing step of causing the first dispensing probe to dispense a second solution in which a coloring matter is not dissolved to a second container different from the first container;
a first sucking and discharging step of causing a second dispensing probe different from the first dispensing probe provided in the dispensing apparatus to suck the first solution in the first container and discharge the sucked first solution from the second dispensing probe;
a second sucking and discharging step of causing the second dispensing probe to suck the second solution in the second container and discharge the sucked second solution from the second dispensing probe;
a step of calculating an amount of the coloring matter collected by the second solution, the coloring matter remaining on the second dispensing probe, by calculating an amount of the coloring matter contained in the second solution discharged from the second dispensing probe; and
a step of evaluating a surface state of the second dispensing probe based on the amount of the coloring matter collected by the second solution,
wherein the test method further comprises a first washing step of washing the first container by using a washing mechanism after the first sucking and discharging step is completed, and
wherein
at a time before the first dispensing step and the second dispensing step, the first solution and the second solution are contained in a bottle of which an inside is partitioned by a partition,
the first dispensing probe includes a first arm which is rotatably attached to a support column, and a second arm which is rotatably attached to the first arm,
in the first dispensing step, the first solution is dispensed to the first container from the bottle, and
in the second dispensing step, the second solution is dispensed to the second container from the bottle.
