<p><P>PROBLEM TO BE SOLVED: To solve the problem of a spectroscopic analysis using electromagnetic waves in a terahertz domain, wherein high-accuracy spectrometry cannot be carried out, hitherto in the case of a solid sample because of an influence of interference or sample rotation angle dependence, although a sample is processed into a flat or wedge-shaped pellet shape and then measured; and to solve the problem wherein measurement sensitivity is low in the case of a liquid sample, although the sample is put into a liquid cell or a test tube and then measured. <P>SOLUTION: The shape of a solid sample is allowed to have a pellet shape, having a symmetric curved surface with respect to an optical axis of the electromagnetic waves. Interference or dependence on the rotation angle is reduced, and high-accuracy spectrometry becomes possible. As for a liquid sample, the sample is dropped onto a substrate having a plurality of fine hole parts and then measured. High sensitivity measurement becomes possible also relative to the trace amount of sample, because the electromagnetic waves transmitted through the hole parts is condensed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
