The specific surface area measurement standards formulated at home and abroad are based on the BET test method. Please refer to my country’s national standard (GB\/T 19587-2004) – Gas adsorption BET principle. Method for determining the specific surface area of \u200b\u200bsolid substances Specific surface area detection is actually a relatively time-consuming task. Due to the different adsorption capabilities of the samples, the testing of some samples may take a whole day. If the testing process is not fully automated, the testers will not be able to leave at all times, and must Highly concentrated, observing the instrument panel and operating the knobs. A little inattention will lead to the failure of the test process, which will waste a lot of valuable time of the tester. The F-Sorb 2400 specific surface area tester is an instrument that can truly realize the BET method detection function (both with direct comparison method). More importantly, the F-Sorb 2400 specific surface area tester is the only fully automated and intelligent specific surface area detection equipment in China so far. , its test results are highly consistent with international standards and have good stability, while reducing human errors and improving the accuracy of test results. \ufffd<\/p<\/p>\n
