In domestic has been eliminated. Specific surface area test unified the multi-point BET method at home and abroad, specific surface area measurement standards are developed at home and abroad is based on BET test method, please see our national standard (GB/T 19587-2004) - gas adsorption BET principle of solid material specific surface area measurement methods. Specific surface area testing is actually the more time-consuming jobs, as the adsorption capacity of sample is different, some sample testing may need to spend the whole dayTime, if the test process is not fully automated, the tester can not leave at any time, and should be highly focused, observe the dashboard, control the knob, a little careless will lead to the failure of the test process, which will waste a lot of valuable time of the tester.

F - Sorb 2400 specific surface tester is really able to BET method detection instruments (both direct comparison method), the more important F - Sorb 2400 specific surface tester is by far the only specific surface area of the fully automated intelligent testing equipment, the test results with the international high consistency, the stability is very good also, at the same time reduce the human error, improve accuracy test results. https://www.activated-carbon-pellets.com/ 

High-quality granular activated carbon must have good adsorption performance and strength.wan yang carbon  

Like powdery activated carbon, the adsorption performance of granular activated carbon depends largely on the characteristics of pore structure. The adsorption performance index can be analyzed and characterized by different methods, such as the decolorization performance of activated carbon expressed by methylene blue. Other performance indexes include iodine adsorption value, caramel decolorization rate, etc.

The pore structure characteristics and specific surface area of activated carbon are usually obtained by measuring nitrogen adsorption isotherm at low temperature with adsorption In addition, the adsorption capacity of activated carbon also has a great relationship with its internal pore structure, pore size distribution and surface chemical properties.

Chemical method in addition to certain micropores, macropores, there are more mesopores (transition pores), so it is more suitable for the application of liquid phase, adsorption of larger molecules of substances, such as sugar solution has a good decolorization effect;

When purifying water quality, it can also remove the colored material well and achieve the specified chroma requirements.
