Apparatus for measuring information on particular component
First Claim
1. An information measuring apparatus of a specific component, characterized in that the apparatus comprises:
- a light source, an optical element of emitting light from the light source to a sample and receiving light returned from the sample, a photodetector of detecting light returned to the optical element, and a polarizer set to permit passage of light of a P-polarized component more than light of other polarized components on an optical path between the light source and the photodetector, and information of a specific component in the sample is measured according to light detected by the photodetector.

Abstract
An information measuring apparatus and a measuring method of a specific component are obtained that can achieve high signal strength without being affected by an interfering substance on a surface of a sample.
The information measuring apparatus of a specific component comprises a light source 1, an ATR element 2 of emitting light from the light source 1 to a sample and receiving light returned from the sample, a photodetector 4 of detecting light returned to the ATR element, and a polarizer 3 set to permit passage of light of a P-polarized component more than light of other polarized components on an optical path between the light source 1 and the photodetector 4. Information such as a concentration of a specific component in the sample is measured according to light detected by the photodetector 4.
