<p><P>PROBLEM TO BE SOLVED: To provide an electrochemical infrared spectroscope capable of detecting/identifying a chemical seed having infrared absorption in a low wave number region where a prism itself has infrared absorption, especially a low wave number region of about 1,000 cm<SP>-1</SP>or below. <P>SOLUTION: An electrochemical surface increasing infrared absorbing spectroscope is equipped with a total reflection measuring prism (1), an acting electrode (2) comprising a metal thin film closely bonded to the base of the prism and supplied with an electrolyte (3) on the opposite face of a face, the counter electrode (4) forming a pair along with the acting electrode, a reference electrode (5) for prescribing the potential of the acting electrode and an optical system for condensing infrared rays to the interface of the prism and the acting electrode from this interior of the prism and guiding the infrared rays totally reflected from the interface to a detector to detect the intensity thereof. The prism has a dimension so that the maximum light passage length of infrared rays in the prism becomes 10 mm or below and the optical system has an infrared microscope and an infrared high sensitivity detector with D<SP>*</SP>of 10<SP>9</SP>or above. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
