Spectroscopic analysis device and spectroscopic analysis method

A spectroscopic analysis device, comprising:

• a first analysis unit that performs fluorescence spectroscopic analysis and/or absorption spectroscopic analysis on a first component contained in a liquid sample using a secondary light generated from the liquid sample irradiated with a primary light;
• a second analysis unit that performs Raman spectroscopic analysis on a second component contained in the liquid sample using a secondary light generated from the liquid sample irradiated with a primary light;
• a concentration measurement unit that measures concentrations of the first component and the second component contained in the liquid sample;
• and
• a computer,
• wherein the computer causes the first analysis unit or the second analysis unit to execute analysis depending on the concentrations measured by the concentration measurement unit.

A spectroscopic analysis method, comprising:

• measuring concentrations of a first component and a second component contained in a liquid sample;
• performing fluorescence spectroscopic analysis and/or absorption spectroscopic analysis using a secondary light generated from the liquid sample irradiated with a primary light, when the concentration of the first component is low;
• and
• performing Raman spectroscopic analysis using a secondary light generated from the liquid sample irradiated with a primary light, when the concentration of the second component is high.
