Product details
Beckman Coulter SA3100Specific surface area and pore size analyzerWe provide a complete solution for characterizing the surface properties of solid materials. The SA3100 specific surface area and pore size analyzer uses accurate gas adsorption technology to measure the specific surface area and porous properties of solids. Based on the principle of adsorption of gas molecules on solid surfaces, combined with simulation theories such as BET and Langmuir, high-precision analysis of the specific surface area and pore size distribution of porous materials is carried out.
SA3100Specific surface area and pore size analyzerThe calculation process is very simple. Generally, before analysis, the surface of the solid needs to undergo pre-treatment. The pre-treatment process is to remove impurities originally adsorbed on the solid surface of the sample under high temperature and vacuum conditions, in preparation for surface adsorption analysis. This process is also known as degassing. Place the preprocessed sample in the analysis position. During the analysis process, the program automatically controls the input of gas, and the gas is intermittently sent to the sample chamber. Due to the low temperature of the liquid surrounding the sample chamber, the activation energy for gas adsorption analysis decreases. A large number of molecules naturally remain on the surface of solid samples. With multiple gas injections, the gas molecules adsorbed on the surface of the sample and the gas pressure around the sample increase accordingly. During the analysis process, the instrument measures the gas pressure and adsorption capacity at each equilibrium state, and represents these data using coordinates to obtain an isotherm. The analysis results of specific surface area and pore size distribution can be obtained by calculating the isothermal line using theoretical models such as BET.
SA3100It is a gas adsorption analyzer with complete functions, high analysis accuracy and speed. Whether for quality control or research and development, SA3100 is a wise choice.

Main features: | |
-Fully intelligent design, fully automated system truly achieves off machine analysis. | |
-The design of the touch screen can display real-time instrument pipeline diagrams, valve actions, sensor readings, isotherms, and ongoing status, as well as be used to set specific surface area and aperture analysis methods and diagnostic instruments. | |
-Compatible with multiple gas analyses without the need for attachments, nitrogen, argon, and krypton can be used for adsorption analysis as needed. | |
-The unique "concurrent gas injection" technology fully improves analysis efficiency and saves analysis time. This technology utilizes the equilibrium time during the sample adsorption process, while balancing the air pressure in the manifold, so that the next gas injection and adsorption process can proceed sequentially. Because the amount of adsorbed gas each time needs to be calculated using the volume of the manifold and the equilibrium pressure. | |
-The isotherm memory function makes the analysis of similar samples extremely fast. Being able to remember the analyzed isotherms allows the instrument to refer to the most suitable gas injection program when reanalyzing similar samples, achieving the goal of saving time. And improve the efficiency of quality control analysis work. | |
-The static gas injection method is used to provide sufficient equilibrium time for the adsorption process of the sample, ensuring the accuracy of the specific surface area and pore size analysis results. | |
-The rapid helium dead space calibration technology makes the analysis results more reliable and accurate (especially for samples with small specific surface areas). | |
-In response to the instability of the reference tube, the instrument is specifically designed to measure the saturation pressure at each time the sample pressure data is obtained, in order to ensure the accuracy of the relative pressure (sample pressure/saturation pressure) data for each group. | |
-Powerful and flexible software controls all functions, and can display pressure readings and isotherms in real-time during the analysis process. | |
-SA View software and Sorption Analysis software provide you with various functions such as data storage, comparison, and printing. | |
-The Sorption Analysis software has multiple user identity selection and a four level data security system to ensure the authenticity of data. The software complies with the electronic record and electronic signature guidelines (21 CFR Part 11) formulated by the FDA, and the recorded data can be converted into files in different formats for easy communication of analysis results. | |
