Title:
SPECTROPHOTOFLUOROMETER
Document Type and Number:
WIPO Patent Application WO/2013/046418
Kind Code:
A1
Abstract:
[Problem] To provide a spectrophotofluorometer which can be applied even to a sample of unknown excitation wavelength, etc. [Solution] A spectrophotofluorometer according to the present invention comprises: a light source (1); a sample cell (3); an excitation-side spectrum assembly (2) which splits light from the light source (1) into a spectrum, and projects light of a desired wavelength upon the sample cell (3); an exit-side spectrum assembly (4) which is positioned in a location wherein light which enters the sample cell (3) from the excitation-side spectrum assembly (2) and which passes through the sample cell (3) is excluded from the light path splits light which exits from the sample cell (3) into a spectrum; and a light detector (5) which is capable of detecting exit light among the exit light from the exit-side spectrum assembly (4) which is of the same wavelength as the light which is projected from the excitation-side spectrum assembly (2) upon the sample cell (3). A set wavelength of the spectrum assemblies (2, 4) when a diffuse light quantity which is detected with the light detector (5) is reduced is an absorption wavelength of the measurement sample, and thus, it is possible to measure the absorption characteristics of an unknown sample.
