Fluorescent whitening agent detector

2024-05-06 17:19

The fluorescence whitening agent rapid measuring instrument is suitable for detecting fluorescent whitening agents in edible mushrooms, packaging bag whitening agent contamination, aflatoxin additives, fruits, poultry eggs, and other substances. If fluorescence is generated after being irradiated by a UV light source in the dark box of the fluorescent whitening agent rapid measuring instrument in the tested sample, it can be determined that the tested sample contains fluorescent whitening agent.

Detection principle:

The whitening effect of the fluorescent whitening agent rapid measuring instrument is to use the principle of chemical complementary color, so that after being treated with fluorescent whitening agent, the yellowing substance can not only reflect visible light (red, orange, yellow, green, blue, blue, purple), but also absorb ultraviolet light outside of visible light and transform it into visible light with blue purple color, thereby offsetting the original yellow color of the substance and making it clean, white, and pleasing to the eye. Due to the fact that the material basis for fluorescent whitening is ultraviolet radiation, which is rarely produced in light sources in daily life, its whiteness under sunlight is lower than that under light. The fluorescent substance in the fluorescent whitening agent is excited by the light source lamp (xenon arc lamp) of the fluorescent whitening agent rapid measuring instrument to generate excited singlet electrons. When the excited singlet electrons jump back to the vibrational energy levels of the ground state, fluorescence will be emitted, which can be observed in the dark. By determining whether the tested sample can see fluorescence under the illumination of this instrument, it can be determined whether there is a fluorescent whitening agent in the tested sample.
