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.
Single Girder Overhead Crane is a light duty Overhead Crane with capacity commonly under 20t, while the Max. capacity reaches 80t. Single girder overhead crane is composed of main girder, end carriage, Electric Hoist and Electric Parts.
