System for real-time measurement of photochemical production systems

A system for measuring a photochemical reaction comprising:

• a photoreactor having a fluid channel configured to transfer a fluid from an inlet to an outlet, wherein said fluid comprises a photosensitizer and a reactant;
• a fluid detection assembly positioned at the inlet and/or outlet of said fluid channel comprising:
• a light source configured to direct light energy through said fluid in the fluid channel;
• at least one photodiode positioned adjacent to said fluid channel and configured to generate an electrical signal in response to the light energy produced by the light source;
• a controller, electrically connected to said one or more photodiodes, configured to convert said electrical signal to a sensor signal that corresponds to said light energy passing through the fluid.

A system for detecting emitted light comprising:

• a fluid channel configured to transfer a fluid containing at least one reactant;
• and
• at least one light source positioned adjacent to the fluid channel;
• a light detection assembly comprising:
• one or more sensors positioned adjacent to the light source and configured to detect the light energy produced by the light source;
• a controller electrically connected to said one or more sensors, configured to generate a signal that corresponds to said wavelength of the light energy or the color spectra of the fluid.
