With the development of social economy and the progress of science and technology, people are paying more and more attention to food safety. Food safety issues are not only related to people's health, but also related to the country's economic development and social stability. Therefore, food safety testing has become an important job. Among the many food safety testing methods, ultraviolet-visible spectrophotometer has been widely used in the field of food safety testing because of its high sensitivity, high accuracy and easy operation.
The T-N5000 UV-Vis spectrophotometer is an instrument that uses substances to quantitatively analyze the absorption characteristics of UV-Vis light. It determines the amount of a substance in a sample by measuring how well it absorbs light at a particular wavelength. T-N5000 has the advantages of high sensitivity, high accuracy, easy operation and wide application range.
1. Ultraviolet-visible spectrophotometer T-N5000 instrument features:
1. The large screen displays various scanning curves and maps, so that users can complete all measurement needs without the help of a computer.
2. The data measured by the user can be directly exported to the U disk, and the opening and editing of the data do not need any professional auxiliary software support, and can support excel, txt, ** format (four formats can be output: ..)csv、.qua、.tet、.BMP), which is convenient for users to edit the experimental report directly on the PC, saves the space of the university laboratory bench, and is convenient for users to use.
3. Using advanced 32-bit Cortex M3 processor, the main frequency reaches 120M, and 5000 test data or 500 working curves can be stored inside the instrument.
4. The instrument is equipped with 8GB memory as standard, which can store test data in large quantitiesThe instrument is equipped with a print interface (232), a host USB interface, and a standard USB (A) interface.
Hour ultra-long life light source, the instrument automatically switches the light source according to the measurement needs, automatically records the use time of the light source, and the socket light source makes the replacement operation simple.
mm high-efficiency planar holographic grating, low stray light.
7. Large sample chamber and a variety of accessories are convenient for users to meet their various measurement needs.
8. It can be directly connected to the printer to output measurement maps and data.
9. Powerful PC function software.
10. The instrument can support remote upgrade and user network upgrade.
2. In food safety testing, T-N5000 ultraviolet-visible spectrophotometer is mainly used in the following aspects:
1. Pesticide residue detection.
Pesticides are a plant protection agent commonly used in agricultural production to control pests and diseases. However, the issue of pesticide residues has always been a key issue in the field of food safety. Excessive pesticide residues can cause harm to human health and even cause serious diseases. UV/VIS spectrophotometer can quickly and accurately determine the amount of pesticide residues in food, providing food safety assurance.
2. Additive testing.
Food additives are substances added to improve the color, aroma, taste, morphology and other characteristics of food, and improve the quality and shelf life of food. However, the excessive use or misuse of some food additives can have health effects on consumers. UV/VIS spectrophotometer can be used to detect the content of preservatives, pigments, sweeteners and other additives in food to ensure food safety.
3. Heavy metal pollution detection.
Heavy metal pollution is an important problem in the field of food safety. Heavy metal contaminants can enter the human body through the food chain and cause serious harm to human health. Ultraviolet-visible spectrophotometer can be used to detect the content of heavy metal elements such as lead, cadmium, and mercury in food, providing food safety assurance.
4. Nutrient content testing.
The nutrients in food are essential for human health. UV/VIS spectrophotometers can be used to detect the content of proteins, fats, sugars and other nutrients in food, providing consumers with accurate nutritional information.
5. Microbial detection.
Microbial contamination is an important problem in the field of food safety. Microbial contamination can lead to food spoilage, spoilage, and even foodborne illness. Ultraviolet-visible spectrophotometer can be used to detect the number of microorganisms such as E. coli and Salmonella in food, providing food safety assurance.
In conclusion, UV/VIS spectrophotometers have a wide range of application prospects in the field of food safety testing. With the continuous development of science and technology, the performance of ultraviolet-visible spectrophotometer will be further improved, and its application in the field of food safety testing will be more extensive. At the same time, we should also strengthen the supervision of food safety, improve the level of food safety, and ensure the food safety of the people.
