Provided is a technology capable of acquiring a measurement result with high reliability under a condition exhibiting a large fluctuation in ambient temperature when measuring numerical value information on a specified substance in a sample. An analysis apparatus includes: a signal detection unit to continuously detect signal values detected from a first sample; a measuring unit to measure numerical value information on a specified substance in a second sample; a first temperature detection unit to capture a first temperature value defined as temperature information on the first sample; a second temperature detection unit to capture a second temperature value defined as temperature information on the second sample; and a calculation unit to calibrate to the numerical value information on the specified substance in the first sample from the signal value by referring to the numerical value information on the specified substance in the second sample in accordance with the first temperature value and the second temperature value.
