The surface area of non-ferrous metals is also very important. The detection data of non-ferrous metals specific surface area is only true and reliable when measured by the BET method. There are many instruments in China that can only perform direct contrast testing and are now eliminated in China. At present, the domestic and foreign specific surface area tests adopt the multi-point BET method, and the specific surface area measurement standards formulated at home and abroad are based on the BET test method. Please refer to the Chinese national standard (GB/T 19587-2004) - BET principle of gas adsorption. A method for determining the specific surface area of a solid material.

The specific surface area measurement is actually a time-consuming task. Due to the difference in the adsorption capacity of the sample, the testing of some samples may take a whole day. If the testing process is not fully automated, the tester can never leave and must High concentration, observing the instrument panel, and manipulating the knob, a little inattentiveness can lead to failure of the test process, which can waste a lot of valuable time for the testers. The truly fully automated intelligent surface area tester product meets the international standards of the testing instrument industry. All the same international products are fully automated. Manually operated instruments have already been eliminated abroad. Really fully automated intelligent surface area analyzer products, freeing testers from repeated mechanical operations, greatly reducing their work intensity, simplifying training, improving work efficiency, and truly fully automated intelligent surface area analyzer product , greatly reducing the human error caused by the operation and improve the test accuracy. The F-Sorb 2400 Surface Area Tester is an instrument that can truly realize the BET detection function (both with direct comparison method). The more important F-Sorb 2400 surface area tester is by far the only fully automated and intelligent surface area detection device in China. Its test results are very consistent with international standards, and its stability is also very good. At the same time, it reduces human errors and improves the accuracy of test results. The detection of specific surface area must follow the relevant standards, methods and theories. The specific details can be further understood in related websites.
