Fluorescence analysis optical multiplexer/demultiplexer, fluorescence analysis optical module, fluorescence analyzer, fluorescence/photothermal conversion spectroscopic analyzer, and fluorescence analysis chip

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 systemas the fluorescence analyzer is comprised of a fluorescence analysis optical module, a probethat condenses exciting light onto a sample solution in a channelinside a fluorescence analysis chip, and a sample stageon which the fluorescence analysis chipis mounted. The fluorescence analysis optical moduleis comprised of an exciting light sourcethat outputs exciting light of dominant wavelength λ, a fluorescence analysis optical multiplexer/demultiplexerfor use in the fluorescence analyzer which analyzes fluorescence of dominant wavelength λ(λ>λ) emitted from the sample upon the sample being irradiated with the exciting light via the probe, a detectorthat receives the fluorescence, an optical fiberthat connects the fluorescence analysis optical multiplexer/demultiplexerto the exciting light source, an optical fiberthat connects the fluorescence analysis optical multiplexer/demultiplexerto the probe, and an optical fiberthat connects the fluorescence analysis optical multiplexer/demultiplexerto the detector. The channelthrough which the sample solution is passed is coated with a reflective metal film
