ABSTRACT:
A fluorescence analysis optical multiplexer/demultiplexer, a fluorescence analysis optical module, a fluorescence analyzer, a fluorescence/photothermal conversion spectroscopic analyzer, and a fluorescence analysis chip, according to which LIF analysis can be carried out easily and with high sensitivity, and moreover photothermal conversion spectroscopic analysis can be carried out easily and simultaneously with the LIF analysis. A microchemical system100as the fluorescence analyzer is comprised of a fluorescence analysis optical module100a, a probe50that condenses exciting light onto a sample solution in a channel204inside a fluorescence analysis chip20, and a sample stage21on which the fluorescence analysis chip20is mounted. The fluorescence analysis optical module100ais comprised of an exciting light source53that outputs exciting light of dominant wavelength λ1, a fluorescence analysis optical multiplexer/demultiplexer56for use in the fluorescence analyzer which analyzes fluorescence of dominant wavelength λ2(λ2>λ1) emitted from the sample upon the sample being irradiated with the exciting light via the probe50, a detector54that receives the fluorescence, an optical fiber106that connects the fluorescence analysis optical multiplexer/demultiplexer56to the exciting light source53, an optical fiber107that connects the fluorescence analysis optical multiplexer/demultiplexer56to the probe50, and an optical fiber108that connects the fluorescence analysis optical multiplexer/demultiplexer56to the detector54. The channel204through which the sample solution is passed is coated with a reflective metal film205.
