How to choose a suitable photochemical reaction instrument

Photochemical reactorAlso known as a photochemical reactor, a multifunctional photochemical reactor It is mainly used to study photochemical reactions under conditions such as gas or liquid media, fixed or flowing systems, ultraviolet light or simulated visible light, and whether the reaction vessel is loaded with TiO2 photocatalyst. It has the functions of providing samples for analyzing reaction products and free radicals, determining reaction kinetic constants, and measuring quantum yields, and is widely used in research fields such as chemical synthesis, environmental protection, and life sciences.

Application fields of photochemical reactors:

The xenon lamp light source of photochemical reactors is widely used in research fields such as water splitting for hydrogen production, photodegradation of pollutants, various simulated sunlight visible light acceleration experiments, and various simulated sunlight ultraviolet band acceleration experiments. Xenon lamp light source can achieve high energy density and long-term continuous irradiation. By combining various filters, multiple combination methods can be achieved to evaluate the improvement effect of narrow band catalysts and the overall catalytic effect of wide band filters. Xenon lamp light source products can be used with various reactors (systems) to complete online and offline analysis experiments of solid, liquid, and gas phases.

How to choose a photochemical reactor or xenon lamp light source?

Xenon lamp light source: Parallel light sources are usually processed by optical devices through light bulbs, while ellipsoidal reflecting mirrors are used in high-energy applications.

In photochemistry, a parallel light source and a reflective sample can form an external irradiation system (light is irradiated from the outside to the inside of the reflective system in the form of a parallel beam).

As for which light sources can form a converging point light source, the central diverging light source and parallel light source need to be discussed on a case by case basis.

Four light source convergence point light sources are commonly used for monochromator spectroscopy, fiber introduction, or energy concentration effects using focal points (such as thermal effects).

5. The light source of a photochemical reactor is usually a diffuse light source that has not undergone any treatment on the lamp source (the light diverges into the entire space in the form of spherical waves). In photochemistry, a cold trap and a reactor are usually used to uniformly radiate light towards the reflecting substance, forming the so-called internal irradiation system (in the entire system, light is irradiated from the inside out).

Advantages of photochemical reactor products: The electrical control part of the product is separated from the protective reaction chamber, making assembly, maintenance, and upgrading convenient and reasonable. The whole machine is atmospheric and beautifulThe main control power controller of this model has flexible digital control of lighting time, suitable for timing operations and data comparison experiments! Professional and stable simulated light sources, as well as stable and space saving volume design, are particularly suitable for laboratory equipment with limited space.
