    摘要: A liquid membrane 100 is formed by jetting a liquid sucked from a recovery reservoir 11a and pressurized using a pump 12 from a nozzle of a liquid membrane cartridge 20. The formed liquid membrane 100 makes contact with a slope wall of the liquid membrane cartridge 20 along a surface of the liquid membrane 100. The liquid running down from the slope wall is recovered and stored in the recovery reservoir 11a in order to recover the liquid running down along the slope wall in a decelerated state into the recovery reservoir 11a. As a result, it is possible to prevent air bubbles from being generated by agitation of a liquid of the recovery reservoir 11a when the liquid enters the recovery reservoir 11a.

    摘要: A terahertz wave is spectrally dispersed into two waves which are caused to pass through a sample liquid film 101 and a reference liquid film 102 and are then collected, and the terahertz waves in an interference state are detected by a terahertz wave detecting semiconductor 15. Consequently, only spectroscopic information related to a distinctive characteristic of the sample liquid film 101 is detected. In addition, a predetermined optical path length difference is provided between a path where the terahertz wave is transmitted through the sample liquid film 101 and a path where the terahertz wave is transmitted through the reference liquid film 102 by an optical delaying unit 17. Ina frequency spectrum obtained by performing Fourier transformation over a terahertz wave signal having an interference waveform by a terahertz wave signal analyzing device 20, consequently, a feature caused by an interaction of dissimilar molecules in the sample liquid film 101 appears in a spectral intensity at a frequency depending on the optical path length difference.
