Abstract

A fluorescence measuring device having a structure for easily measuring fluorescence of a trace sample in a short time. The fluorescence measuring device comprises an excitation light source, a pipette unit, a chip attached to the pipette unit, and a fluorescence detection system. The pipette unit consists of a pipette and a pipette adapter having a structure for introducing excitation light into the internal space of the pipette adaptor, and a fluorescent sample taken in from a suction opening is held at the forward end of the chip. Excitation light from the excitation light source is irradiated by the excitation light introduction structure to the fluorescent sample at the forward end of the chip through the internal space of the pipette adapter, and fluorescence is emitted from the fluorescent sample. The fluorescence detection system receives at least a part of fluorescence generated through the excitation light irradiation.

Description

technical field [0001] The present invention relates to a fluorescence measurement device for detecting fluorescence emitted from a sample irradiated with excitation light. Background technique [0002] In many fields such as the pharmaceutical industry, the food industry, the chemical industry, and the agriculture, forestry, and fishery industries, when conducting research and development of new drugs, screening of enzymes, and analysis of trace functional substances in the body such as physiologically active substances, experiments are performed by measuring fluorescence. material analysis. In the bio-related field, when analyzing important biological samples such as nucleic acid or protein, in many cases the biological sample to be measured is only a trace amount. In addition, since the quantification of the sample is also very important, for example, by the following method for analysis. [0003] That is, in the fluorescence measurement of the prior art, adopt Figure ...
