Protein is one of the most important nitrogen-containing biological macromolecules in cells and bears various biological functions. Therefore, quantitative analysis of protein is a very important task in the aspects of quality analysis of agricultural and pastoral products, comparison of nutritional value of food, biochemical breeding, and clinical diagnosis. There are many methods for the determination of proteins. The commonly used methods are nitrogen determination, double urination, phenol reagent method, and ultraviolet absorption method. Among them, the determination of nitrogen is widely used in the fields of grain and oil quality detection because of its accurate measurement. However, the method of determining nitrogen is more complicated and the application threshold is relatively high. In order to determine the protein content more conveniently, many industries currently use protein analyzers to determine the protein content of a sample.
The determination of the nitrogen determination method is complicated and the operation is cumbersome, while the protein analyzer is based on the nitrogen determination method, optimizes the process steps of the operation, and gives full play to the important role of scientific and technological instruments in traditional detection methods. Compared with the traditional determination of protein content in the nitrogen determination method, the protein analyzer enables the determination of protein content by the method of determination of nitrogen to be simple and efficient, which not only greatly increases the range of determination of protein content, measurement efficiency, measurement accuracy, and determination. The stability and safety of the assay have also been further enhanced, allowing the assay personnel to perform this task in a safer environment.
In fact, any method is not perfect, the instrument is the same, in order to make better use of nitrogen determination of protein content, for scientific research, quality inspection and other work to provide scientific and effective test data, since the introduction of protein analyzer, is also constantly For technological updates and technical optimization. With the advancement of science and technology and the development of society, in recent years, more automated protein analyzers have been developed and applied to industry research. Some of the complex and dangerous work processes can be performed by instruments. To be completed, this is not only the convenience brought by science and technology, but also the simple and efficient development of the times.
The vacuum drying oven(vacuum tray dryer) is a static dryer. It is used to dry fruit, vegetables, chemical product or pharmaceutical product. As it works in low temperature and high vacuum, it can yield high quality product.
Vacuum drying oven is widely applicable for drying and sterilization in fields of biochemistry, pharmacy, medicine and health, agriculture and scientific research and environment protection. It is designed specially for drying of material which is thermo-sensitive and oxidative easily.
- It has follow advantages compare with the routine dry technology:
- Vacuum environment greatly reduced the liquid boiling point which needs to drive out, therefore the vacuum dry method is applicable for heat sensitivity material;
- For the sample that can't be dried easily, such as powder or other pellet form sample, using vacuum dry method may efficiently shorten dry time;
- Various complex structures of machinery ministry or other porous sample process are used of vacuum dry method after washing, and Completely dry without leaving any residue;
- Use more safe: under vacuum or inertia condition, completely eliminate the possibility that the oxide heated and explode;
- Compare with the normal drying depended on air cycle, Powder samples will not be blown or moved by air
