Optical Analysis Apparatus, Manufacturing System for a Substance, and Manufacturing Method for a Substance

A manufacturing system for a substance, comprising:

• a vessel which is configured to store a first substance;
• a flow passage, which is connected to the vessel, and is configured to allow the first substance to flow therethrough;
• an introduction unit, which is provided to the flow passage, and is configured to introduce at least two second substances to the flow passage, to thereby divide the first substance flowing through the flow passage;
• and
• a measurement unit, which is provided to the flow passage, and is configured to perform measurement by irradiating the first substance and the second substances flowing through the flow passage with light.

A manufacturing method for a substance, comprising:

• storing a first substance in a vessel;
• allowing the first substance to flow through a flow passage connected to the vessel;
• dividing the first substance flowing through the flow passage by introducing at least two second substances to the flow passage from an introduction unit provided to the flow passage;
• and
• performing measurement by irradiating the first substance and the second substances flowing through the flow passage with light from a measurement unit provided to the flow passage.
