Limitations
Pore Size Distribution
While it can determine surface area accurately, BET analysis might not provide detailed information on the distribution of pore sizes.
Assumption of Ideal Monolayer
The method assumes the formation of an ideal monolayer of adsorbed gas molecules, which might not hold true for all materials, impacting accuracy.
Sample Preparation
Sample preparation is critical, and factors such as surface cleanliness and proper degassing can affect the results.
Limited to Specific Materials
The applicability of BET analysis is limited to materials that exhibit physical adsorption characteristics with the gas used for measurement.
Applications
》Super micro powder, nanomaterials, particle and fiber shaped specific surface area analysis.
》Product quality control for powder materials related corporations.
》Research institutes, universities for BET theory teaching.
》Full cells, catalysts, additives, adsorbent, ceramics, magnetic materials, energy storage materials etc.
》Other researches concern surface area performance.
Performance Indicators
Test function:Static volumetric principle，adsorption/desorption isotherms measurement，single and multi-point BET method，Langmuir method, BJH total pore volume and pore size distribution analysis，DR and DA filling theory, t-plot external surface area measurement，true density measurement；powerful online data analysis system and specific surface area and pore size distribution test system to ensure more stable and accurate test data.
Sample number:Two samples tested at same time and two samples’ degassing treatment，the sample testing system and sample processing system are independent; sample testing and sample processing can be carried out simultaneously, avoiding the contamination of the test pipeline, further ensuring the accuracy of the test and improving the service life of the instrument.
Test mode:Integrated "Single nitrogen test mode" and "Nitrogen + helium standard test mode", for customers to choose according to actual needs；using "Nitrogen + helium standard test mode" in line with international standards, can ensure the accuracy and consistency of results, and easy to operate；for samples that can adsorb helium at low temperature, helium gas is not suitable for determination of free space，"Single nitrogen test mode" can get the desired test results.
Test gas:High purity N2gas or other (Ar, Kr are optional)
Vacuum pump:Imported two-stage vacuum pump can be external and built-in; the built-in vacuum pump can be automatically controlled by the software according to the experimental needs, so as to extend the life of the vacuum pump.

Test accuracy |
Specific surface area repeatability error ≤±1.0% |
The high vacuum micro welding pipeline system has compacted pipeline connection and small dead volume space VCR interface parts with metal surface seal overcome the problem of self outgassing of O-ring seal under low vacuum.
The supporting VCR interface pneumatic valve eliminates the measurement error caused by local heating of the electron magnetic valve.
The electropolished method of pipe wall in the whole system ensures the air leakage rate to reach the requirements of 1 * 10-10pa.m3/s under high vacuum.
Digital pressure measurement and data acquisition system
The pressure and temperature sensor with digital output has twice the accuracy of similar products with analog output and stronger anti-interference ability.
Industrial standard RS485 or RS232 communication mode, sensors are added on demand on the communication bus, with high scalability.
The high-precision digital pressure sensor has a pressure output resolution of 1Pa, conducive to improving the test accuracy compared with the 4pa resolution commonly used in the same industry.
