Concentration measuring instrument, concentration measuring contact apparatus, concentration measuring calculating apparatus, and concentration measuring method

A concentration measuring method of measuring a specific component contained in a subject of measurement comprising:

• a contacting step of bringing the concentration measuring contact into contact with the subject of measurement;
• a light entering step of entering light into the concentration measuring contact;
• a measuring step of measuring at least the quantities of the p-polarized light component and the s-polarized light component of the light that is passed through the concentration measuring contact into the subject of measurement, transmitted in the subject of the measurement, and returned to the concentration measuring contact;
• and
• a calculating step of calculating the concentration of the specific component contained in the subject of measurement based on the determined results in the measuring step.

A concentration measuring contact apparatus including:

• a concentration measuring contact that is brought into contact with a subject of measurement;
• a light source that emits light and enters the light into the concentration measuring contact;
• a polarizer that takes out p-polarized and s-polarized light components of the light that is passed through the concentration measuring contact into the subject of measurement, transmitted in the subject of measurement, and returned to the concentration measuring contact;
• and
• a photodetector that determines at least the quantities of the p-polarized light component and the s-polarized light component taken out by the polarizer, wherein the concentration of a specific component contained in the subject of measurement is calculated by calculating means based on the determined results.
