Abstract: [Problem] To provide a fluorescence detection apparatus that is capable of simultaneously detecting a plurality of analyte components contained at different concentrations with a wide measurement range. [Solution] A fluorescence detection apparatus 100 includes a cell 110 into which an analyte of a sample is introduced, a light source 130 that irradiates excitation light on the analyte in the cell; a first detector 52 that detects fluorescence generated from the analyte after the excitation light has been irradiated on the analyte, and a second detector 53 that detects the fluorescence generated from the analyte after the excitation light has been irradiated on the analyte. The second detector detects the fluorescence with a measurement range that is different from the measurement range of the first detector, and the first detector and second detector detect the fluorescence simultaneously.

Abstract: An evaluation method for evaluating an ultraviolet radiation protection effect in a measurement sample applied on an application member includes the first step of switching to a first filter for measuring a spectral transmittance before photodeterioration by emission of light from a light source, and measuring the spectral transmittance, the second step of switching to a second filter for ultraviolet irradiation and causing the photodeterioration by the emission of the light after the measurement by the first step, and thereafter, switching to the first filter and measuring the spectral transmittance, and the third step of evaluating the ultraviolet radiation protection effect based on a change over time in the spectral transmittance obtained by the second step. Each of the first and second filters includes multiple light source filters. The first filter includes ND filters switchable in accordance with the light amount of the light source in the light source filters.
