First Claim
1. A component concentration meter that measures a concentration of a target component contained in an object to be measured, the component concentration meter comprising:
- an output unit configured to output an electromagnetic wave to the object to be measured;
a detecting unit configured to detect a property of the electromagnetic wave passed through the object to be measured under a first condition and under a second condition in which a temperature of the object to be measured is different; and
a concentration determining unit configured to determine the concentration of the target component contained in the object to be measured, based on (i) a property difference which is a difference between a property of the electromagnetic wave detected by said detecting unit under the first condition and a property of the electromagnetic wave detected by said detecting unit under the second condition, and (ii) a difference between the temperature of the object to be measured under the first condition and the temperature of the object to be measured under the second condition,wherein said output unit is configured to output an electromagnetic wave for detection that has a first wavelength and passes through the object to be measured to be detected by said detecting unit and to output an electromagnetic wave for heating that has a second wavelength and is absorbed by the object to be measured to increase the temperature of the object to be measured,wherein the electromagnetic wave for heating has an absorption by the object to be measured that is larger than an absorption of the electromagnetic wave for detection, andwherein the difference between the temperature of the object to be measured under the first condition and the temperature of the object to be measured under the second condition is caused by said output unit outputting the electromagnetic wave for heating to the object to be measured.

Abstract
An component concentration meter includes an output unit that outputs an electromagnetic wave to an object to be measured and includes a detecting unit that detects the property of the electromagnetic wave passed through the object to be measured under a first condition and under a second condition in which the temperature of the object to be measured is different from that under the first condition. The component concentration meter also includes a concentration determining unit that determines the concentration of a target component contained in the object to be measured, based on a property difference which is a difference between the properties of the electromagnetic wave detected by the detecting unit under the first condition and under the second condition and a difference between the temperatures of the object to be measured under the first condition and under the second condition.
