Test gas types: N2, and other adsorbed gases CO2, Ar, Kr, He, methane (CH4), benzene (C6H6), toluene (C7H8), ethanol (C2H5OH), etc .;
P0 test: It has an independent saturated vapor pressure (P0) test station to ensure high accuracy of partial pressure test;
Pressure test: original imported pressure sensor; pressure test range 0-1.6bar (0-160KPa), accuracy error ≤0.15%; micro-hole section partial pressure P / P0 can reach 1 * 10-7, the number of points is greater than 50; large holes The segment has the real-time testing function of P0, so that the control accuracy of P / P0 when approaching the spirit boundary reaches 0.998.
Sample pretreatment: Simultaneous processing of sample quantity: 2; Two-way degassing station has independent temperature control and independent timing function, which can support sample degassing processing of different temperatures and different times synchronized with the test;
Sample pretreatment mode: It has the only two optional functions of "ordinary heating and vacuum molecular diffusion mode" and "molecular replacement mode"; the molecular replacement mode has more than doubled the efficiency of the molecular diffusion mode, and can save more than half of the pretreatment Time to solve the problem of long sample preparation time in the past static method;
Test efficiency of activated carbon pore size distribution analyzer: intelligent gas flow control, small and medium adsorption samples 2-3min / partial pressure point, medium and large adsorption samples 3-5min / partial pressure point; BET multi-point method 15-30min / 1 sample ; BET single point method 6-10min / 1 sample; standard pore size test 60-120min / 1 sample; fine pore size test 120-300min / 1 sample; the above test time does not include sample pretreatment time;
Liquid nitrogen surface control: It has a liquid nitrogen surface servo holding system, which eliminates the change in the dead volume caused by the liquid nitrogen surface change caused by the liquid nitrogen volatilization during the test process, and improves the test accuracy;
Graphical control interface: Affinity control and monitoring interface, showing the complex working state of the instrument in the form of structure diagram, so that the working state of the instrument can be seen at a glance, and various valves, vacuum pumps, nitrogen cup lifts, temperature Control and wait for all hardware to operate, pleasing to the eye;
