<p>PROBLEM TO BE SOLVED: To provide an ATR analysis method improved to perform a practical analysis with high sensitivity and an optical prism therefore. SOLUTION: A sample 101 is arranged at least on the first reflective face 7 of an optical prism 100 having a light incoming window 5, a light outgoing window 6, the first reflective face 7, and a second reflective face 8 for multiple reflecting the light multiple reflected on the first reflective face 7 at least one more time on the first reflective face 7. An incident light 2 entering from the incoming window 5 is reflected totally on the interface between the first reflective face 7 of the optical prism 100 and the sample 101 and the outgoing light 3 outgoing from the outgoing window 6 is detected by a detector 4 thus analyzing the sample 101.</p> |
