Brief introduction:

Fluorescent brightener detector is suitable for the detection of edible fungi fluorescent whitening agent, packaging bag whitening agent pollution, aflatoxin additives, fruits, eggs, etc. In the food industry, the color protection of Lentinus edodes, mushrooms and edible fungi, fluorescent whitening agent, aflatoxin, food additives, deteriorated vegetables, fruits, cocoa butter, chocolate, fat, honey, sugar, eggs, paper cups and food packaging were detected in the food industry. If there is fluorescence after the ultraviolet light source in the instrument dark box of the tested sample is irradiated, it can be judged that there is fluorescent whitening agent in the tested sample.

Details:

The whitening function of the fluorescent whitening agent detector is to use the chemical complementary color principle to make the yellowing substance not only reflect visible light (red, orange, yellow, green, green, blue, purple) after being treated by fluorescent whitening agent, but also absorb ultraviolet light other than visible light, and convert it into visible light with blue and purple to reflect, thus offsetting the original yellow of the object and making it white Pleasing to the eyes. Because the material basis of fluorescent whitening is ultraviolet, which is rarely produced in light source in daily life, the whiteness of fluorescent whitening under sunlight is more white than that under light. Under the illumination of xenon arc lamp of Jiapeng fluorescent brightener detector, the fluorescent substance in fluorescent whitening agent is excited to generate electrons in the first excited singlet state. When the electrons in the excited singlet state jump back to the vibration energy of the ground state, they will emit fluorescence, which can be observed in the dark. The fluorescent whitening agent can be determined by whether the sample can be seen fluorescence under the illumination of the instrument.

Fluorescent brightener detector is suitable for the detection of edible fungi fluorescent whitening agent, packaging bag whitening agent pollution, aflatoxin additives, fruits, eggs, etc. In the food industry, the color protection of Lentinus edodes, mushrooms and edible fungi, fluorescent whitening agent, aflatoxin, food additives, deteriorated vegetables, fruits, cocoa butter, chocolate, fat, honey, sugar, eggs, paper cups and food packaging were detected in the food industry. If there is fluorescence after the ultraviolet light source in the instrument dark box of the tested sample is irradiated, it can be judged that there is fluorescent whitening agent in the tested sample.

Performance advantages:

1. The light emitted by the UV lamp is filtered by the color filter to remove the visible light, which is a strong ultraviolet light for fluorescence analysis.

2. It is controlled by microcomputer

3. The operation is simple, no professional personnel is needed, and the detection speed is fast, and the detection results can be obtained.

4. Mass storage, can store more than 3000 pictures

5. There are two-way operation ports on both sides of the instrument box, and the front door opening design is convenient for taking and placing samples

6. Through the digital camera microcomputer control, the sample is transferred to the computer, and the image is saved, analyzed and inquired

7. Users can directly observe the samples in the darkroom through the box

8. Specially designed anti ultraviolet observation port, so that operators can avoid UV damage

9. USB2.0 interface facilitates data transfer

10. Small size, light weight, easy to carry
