ABSTRACT:
An internal reflectance element (IRE), used for internal reflectance spectroscopy (IRS) of solid or liquid samples, has a body including a very small contacting surface adapted to insure contact with a small portion of the sample to improve the spectroscopic analysis of that sample. The contacting surface of the IRE for solids preferably is 100 microns or smaller in diameter and preferably is convexly curved. The contacting surface of the IRE for liquids preferably is 500 microns or smaller. The IRE of the present invention is most frequently used in single internal reflection applications for IRS analysis of solids.
