PROBLEM TO BE SOLVED: To improve measuring sensitivity and measuring reliability by placing a window material and a liquid in non-contact with each other to suppress dissolution of the window material in an infrared spectrometry apparatus using the window material in contact with the liquid.SOLUTION: The infrared spectrometry apparatus according to the present invention includes: a cell formed of a frame material and a polymeric membrane; a window material placed apart from the polymeric membrane of the cell with a clearance intervening therebetween; and a medium layer filling the clearance and having a small solubility with respect to the polymeric membrane. An infrared spectrometric method according to the present invention includes: filling the cell of the infrared spectrometric apparatus with liquid, the infrared spectrometric apparatus including the cell formed of the frame material and the polymeric membrane, the window material disposed apart from the polymeric membrane of the cell with the clearance intervening therebetween, the medium layer filling the clearance and having the small solubility with respect to the polymeric membrane, and an action electrode, a reference electrode, and a counter electrode to be provided in an electrochemical cell; making infrared light incident from the window material thereto; and receiving an exiting reflection light to perform spectrometry. |
