Description

technical field [0001] The invention belongs to the field of photochemistry and relates to a photochemical reaction device, in particular to a mass spectrometer analysis device for high-throughput online photochemical reaction research. Background technique [0002] Photochemistry is a branch of chemistry that studies the permanent chemical effects caused by the interaction of light with matter. Due to historical and experimental technical reasons, the wavelength range of light involved in photochemistry is from 100 to 1000 nanometers, that is, from ultraviolet to near infrared. Since the absorption of photons of a given wavelength is often the property of a group in a molecule, photochemistry provides the best means of reacting at a specific position in the molecule, for those thermochemical reactions that lack selectivity or where the reactants may be destroyed The system is more valuable. Another feature of photochemical reactions is that photons are used as reagents. O...
