Determination of BJH pore size distribution using adsorption curve 

Determination of Brunauer pore size distribution using desorption curve 

Determination of Dubinin- Astakhov pore size distribution using desorption curve 

Accuracy: high accuracy and good reproducibility. Repeatability error of less than ± 2%;

test range: surface area minimum 0.01m2 / g , pore size distribution 0.35-500nm;

sample types: powder, granule, fiber and sheet materials, like this can be put into the sample tube material.

P0 tests: independent saturation vapor pressure (P0) test station, to ensure high accuracy of the partial pressure of the test;

Sample preparation: the number of stations: 2; degassing stations have independent temperature control and definite timing function, test and preparation stations are separated and running independently;

Sample pretreatment modes: "normal heating vacuum molecular diffusion model" and "molecular replacement mode" two optional function; molecular replacement model can save more than half of the pretreatment time;

Test Efficiency: Intelligent air input control, small adsorption sample 2-3min / 1 sub-pressure point, the large adsorption samples 3-5min / 1 sub-pressure point; BET multi-point method 15-30min / 1 samples; BET single-point 6-10min / 1 samples; standard pore size test 60-120min / 1 samples; micropore test 120-300min / 1 samples;

Stress testing: Stress testing range 0-1.6bar (0-160KPa), accuracy error ≤ 0.15%;

Liquid level control: liquid nitrogen level control system, eliminating change of the dead volume in testing process due to evaporation of liquid nitrogen to make liquid nitrogen level changes , improve test accuracy;

Graphical window: friendly control and monitoring system window can show the instrument working details, the various valves, pumps, nitrogen glass elevators, operating temperature and all other hardware can be control by our system;

Intelligent self-test system: hardware self-test and gas tightness self-test, can automatically detect air leak and fix position, gives text and voice prompts.

Voice prompt: unique intelligent voice prompts;

Control system:

1. Stable control system: can save real time data and information,  if communication is lost, unexpected power outages and other unforeseen circumstances, the system can restore the test data ensure you can continue  test;

2. have smart and safe dewar flask lift control system, when power offer equipment  reboot, the system can prevent liquid nitrogen dewar flask descend unexpectedly;

3. vacuum pump control system can reduce noise and prolong pump life;

 4. have detailed operation recording, automatic record each experiment of    actions and processes per second, easy to check and failure feedback;

Data processing:

1. Isotherm analysis with a standard mode, fine mode and custom mode selectable; adsorption can be tested, adsorption-desorption test, and direct access to desorption tests; a variety of optional test theory; each test theories  can be freely selected;

2. Powerful data management and processing systems: all the raw data and test results are saved to a SQL database, support date, operator, sample names and other searching and filtering,data can export as Excel ;

accessories:

1. 40L high purity nitrogen, purity ≥ 99.999%, average service life: 2-3 years;

2. Bei Shi De vacuum,, 5-year warranty, ultimate vacuum: 4 * 10-2Pa;

3. valve, pressure sensor are all high quality;
