What kind of software and hardware conditions and standards are required to achieve fully automated operation?
1. When testing the BET specific surface area and pore size distribution by the nitrogen adsorption continuous flow method, the flow rates of nitrogen and helium gas must be adjusted accurately to achieve the determination of the adsorption amount of the sample under different P / Po nitrogen partial pressures. The sample adsorption capacity under P / Po can calculate the BET specific surface area and pore size distribution results. Therefore, to achieve automatic detection, the instrument needs to have nitrogen and helium flow rates that can be automatically adjusted by the detection software, but manual manual adjustment cannot be automated. F-Sorb X400 series specific surface and pore size analyzer products have a completely automatic flow adjustment by adopting an original flow adjustment system.
2. After the automatic adjustment of the flow rate, the flow signal of the flow sensor can be directly collected through the software in order to perform the related automatic operation judgment and the final theoretical calculation. Then the software cannot perform the condition judgment required for the automated operation, and the automated test cannot be realized. The FF-Sorb X400 series specific surface and aperture analyzer products have completely realized the software acquisition of flow signals by adopting a unique high-precision acquisition system.
3. Due to the inherent characteristics of the thermal conductivity detector, the signal zero will drift during the test. Therefore, the software needs to be able to automatically adjust and correct the signal zero in order to achieve complete automation of the test process. , It is impossible to automate the testing process. F-Sorb X400 series specific surface and aperture analyzer products use the original signal zero drift adjustment system, which has the software automatic adjustment and correction function of the signal zero point.
4. During the detection process, the liquid nitrogen cup needs to rise or fall according to the needs of the experiment in order to achieve the adsorption and desorption of the sample. The test process needs to be automated. It needs to be able to automatically control the rise and fall of the liquid nitrogen cup through the software. The button on the top to control its lifting can't automate the testing process. The F-Sorb X400 series specific surface and pore size analyzer products can automatically control the lifting of the liquid nitrogen cup by using software.
5. During the BET and pore size distribution test, quantitative gas is needed to calibrate the amount of nitrogen corresponding to the desorption peak area. If the quantitative gas is a mechanical valve on the instrument panel, the gas path of the quantitative gas is achieved by manual operation Conversion, the test process cannot be automated. F-Sorb X400 series specific surface and pore size analyzer products can realize the automatic desorption of quantitative gas on demand by using a different mechanical quantitative tube system, so as to fully automate the testing process.
F-Sorb X400 series specific surface and pore size analyzers are the only products in the domestic similar products that can fully automate and automate the testing process. They are in line with international modern instrument manufacturing standards and trends, and have achieved from testing standards, theoretical calculations to manufacturing The standard is fully in line with international products, and is committed to providing cost-effective precision testing instruments for scientific research units and production enterprises in China.
