Near infrared fiber spectrometerWith the advantages of non-contact, fast, and non-destructive testing, as well as the flexible sampling characteristics brought by fiber optic transmission, it has been widely used in material testing in multiple fields such as food, chemical, pharmaceutical, and agriculture, enabling efficient analysis of material composition, purity, quality, and other indicators.

1、 Food industry: Ensuring the quality of ingredients and processed products

Raw material quality screening

In the process of grain procurement, the moisture, protein, and starch content of grains such as wheat, corn, and rice can be quickly detected without the need for crushing and sampling. The detection can be completed by simply placing the fiber optic probe close to the material, greatly improving the efficiency of procurement and sorting; For oil crops (such as soybeans and peanuts), it can accurately determine the oil content and fatty acid composition, and screen out inferior raw materials in advance.

Process monitoring

In dairy production, the fat, lactose, and protein content of milk can be monitored in real time, and processing parameters can be adjusted in a timely manner to ensure batch consistency of the product; In the baking food production line, the moisture and gluten content of the dough can be detected online to avoid problems such as over drying, over wetting, or poor taste in the finished product.

Finished product quality acceptance

For finished products such as edible oil, beverages, and snack foods, it is possible to quickly identify whether they are adulterated (such as adding low-priced oils to edible oil or adding plant protein to milk powder), while testing key indicators such as moisture and sugar, simplifying the cumbersome process of traditional laboratory testing.

2、 Pharmaceutical industry: Control the entire process of drug production

Purity testing of raw materials

For traditional Chinese medicinal materials and chemical raw materials, the content of active ingredients can be quickly determined by near-infrared fiber optic spectrometer, such as detecting alkaloids, flavonoids, or the purity and impurity proportion of chemical raw materials in Chinese medicinal materials. Compared with traditional high-performance liquid chromatography, there is no need for complex pretreatment, and the detection time is shortened from a few hours to a few minutes.

Preparation process monitoring

In the production of tablets, capsules, and other formulations, fiber optic probes can be used to penetrate the mixing equipment and monitor the uniformity of material mixing in real time to prevent unstable drug efficacy caused by uneven mixing; At the same time, it can detect the moisture content of particles to avoid drug deliquescence and deterioration caused by excessive moisture.

Finished product and packaging inspection

For finished pharmaceutical products, it is possible to quickly verify whether the ingredients and content meet the standards; It can also detect the compatibility of ingredients in drug packaging materials (such as plastic bottles and aluminum foil) and investigate whether the packaging materials will transfer harmful substances to the drug.

3、 Chemical industry: improving production efficiency and safety

Raw material incoming inspection

For chemical raw materials such as methanol, ethanol, and various resins, their purity, moisture content, and impurity types can be quickly detected to avoid unqualified raw materials entering the production line and causing product scrap, while reducing the waste of reagents and waste liquid pollution caused by traditional chemical testing.

Online analysis of production process

In polymer production, the monomer conversion rate and molecular weight distribution of the reaction system can be monitored in real time, and parameters such as reaction temperature and pressure can be adjusted in a timely manner to ensure stable product performance; In the production of coatings and adhesives, the proportion of components related to solid content and viscosity can be detected to ensure that the product meets the process requirements.

Waste and finished product testing

For chemical waste, it can quickly identify the components and assist in classification and recycling; For the final products (such as plastic particles and coating products), the consistency of their composition and key performance indicators can be tested to improve the factory qualification rate.

4、 Agricultural sector: Supporting precision planting and agricultural material testing

Crop quality inspection

In the field, portable near-infrared fiber optic spectrometers combined with fiber optic probes can be used for in-situ detection of fruits and vegetables (such as apples, oranges, and vegetables) to determine indicators such as sugar content, acidity, and vitamin C content, achieving rapid sorting of high-quality fruits and vegetables; For harvested cotton, the fiber moisture content and maturity can be detected to guide subsequent processing.

Identification of Agricultural Material Quality

Can quickly detect the nitrogen, phosphorus, and potassium content of fertilizers, and identify counterfeit and inferior agricultural materials; For pesticide raw materials and formulations, the content of active ingredients can be determined to ensure the effectiveness of agricultural inputs and reduce crop yields caused by substandard agricultural inputs.
