Laboratory Specific Surface Area and Pore Size Analyzer

Main Function

1. Full functionality: specific surface area, mesoporous, microporous analysis;
2. High throughput: optional analysis bit rates of 3/6/9/12;
3. Fully automatic: degassing → testing, fully automatic switching;
4. Pollution prevention: micro-porous samples are subjected to pressure-controlled heating to prevent contamination and degassing;
5. Zero helium pollution: first helium gas temperature measurement area, then automatic degassing;
6. Automatic cycle: Automatic evaluation of material cycle adsorption performance.

Technical Parameter

1. Wide testing range: specific surface area above 0.0005 ㎡/g, pore size 0.35-500nm;
2. Testing efficiency: multi-point BET (excluding degassing process), standard mode 12 samples/60 minutes; Rapid testing mode with 12 samples per 15 minutes;
3. High testing accuracy: specific surface area, pore size, pore volume, adsorption capacity, quantitative error<0.5% RSD (based on BET value of standard sample);
4. Program heating and degassing: Software controls program heating, room temperature -400 ℃, accuracy better than 0.1 ℃;
5. Intelligent degassing completion judgment: supports software automatic judgment, automatically judges the degassing effect based on pressure changes;
6. Anti-flying degassing: pressure controlled heating+pressure controlled vacuum pumping, a dual approach, completely solves the problem of sample flying during the degassing process;
7. Vacuum degree: 10-2Pa.

Technical Advantages

1. High throughput and high efficiency: Supports analysis of up to 12 samples at a time;
2. Truly fully automated: the world's first automatic switching between a degassing furnace and a Dewar flask, eliminating the need for manual transfer of sample tubes or degassing furnaces;
3. High time utilization: It solves the problem of wasting time when conventional instruments cannot start testing after degassing is completed after work, making it a reality to install samples after work and check data at work;
4. Thoroughly eliminate "helium pollution": helium gas testing dead volume → vacuum heating degassing → adsorption testing is the first to solve the problem of helium pollution in microporous analysis internationally, improving testing accuracy;
5. Anti-flying degassing: supports "pressure controlled heating"+"pressure-controlled vacuum pumping", automatically adjusts the program heating and vacuum pumping rate according to pressure changes to prevent sample flying;
6. Support automatic cycle testing: automatic degassing+test cycle testing, used to evaluate the stability and lifespan of material adsorption performance;
7. Pressure-controlled temperature rise "anti-flying degassing technology: refers to the programmed temperature rise technology under gas pressure control, which automatically starts and stops the programmed temperature rise according to pressure changes, fundamentally preventing sample flying;
8. The "automatic constant temperature zone" technology: The curve shows that the change rates of the "equivalent volume of the adsorption chamber" after 24 hours of the constant temperature zone effect of the three methods are: BSD temperature zone servo automatic constant: 0.10%, isothermal clamp: 0.25%, liquid level sensor: 0.55%;
9. Convenient installation and sealing: The one-time sealing technology for 6 sample tubes in a single analysis station eliminates the need to seal each tube individually, providing an unparalleled efficiency experience;
10. Full temperature control of the pneumatic system: The internal pneumatic system of the instrument is fully temperature controlled to 40 ℃, with an accuracy better than ± 0.01 ℃;
11. Upward sliding door: Humanized and easy to open and close, saving laboratory space;
12. Electric turbine liquid nitrogen pump: Humanized liquid nitrogen addition, stepless-speed regulation, free movement, safe and convenient, liquid nitrogen pollution-free;
13. High reliability: With an international supplier system, all core components are imported with original packaging;
14. Open data interface: The software can be used in conjunction with Lims to upload test results to Lims.
