Abstract
Disclosed is a spectrophotometry for a spectral transmission measurement of an extremely small volume of sample solution. A sampleris formed of a flat plate member formed with a sample-holding holewhich penetrates the flat plate member in its thickness direction and has a reverse truncated cone shape, and a target sample solution is dropped into the sample-holding holeof the samplerpositioned approximately horizontally and held in the holebased on a surface tension of the sample solution in the form of a droplet S. Then, a measurement light is emitted to the held droplet S from directly above. A transmitted light getting out of the droplet S downward is introduced to a diffraction gratingthrough a window plateand a slit, and dispersed in a wavelength dependent manner. The resulting light with dispersed wavelength components is detected by a multichannel detectorapproximately simultaneously.
