Automatic analyzer

An automatic analyzer comprising:

• a reagent container that contains a reagent;
• an emission unit that is provided outside the reagent container and emits light so as to pass inside the reagent container;
• a light receiving unit that is provided outside the reagent container and receives the light emitted from the emission unit;
• and
• a determination unit that, based on the light received by the light receiving unit, detects a liquid level inside the reagent container, and determines whether a liquid volume in the reagent container becomes equal to or less than a predetermined value from the liquid level, wherein
• a wavelength of the light is a wavelength of near-infrared light determined based on a material of the reagent container and a type of the reagent, and
• an absorbance of light absorbed by the reagent is greater than an absorbance of light absorbed by the container.

• and
• a correction unit that corrects a count value of a liquid volume of a sucked reagent to the predetermined value when the determination unit determines that the liquid volume inside the reagent container becomes equal to or less than the predetermined value, wherein
• a wavelength of the light is determined based on a material of the reagent container and a type of the reagent.
