Overview
The BET specific surface area analyzer uses the continuous flow method (standard comparison method) proposed by Nelsen and Eggertsen as the measurement method. Under the action of low-temperature liquid nitrogen, a helium nitrogen mixture is continuously introduced into the sample tube, and the nitrogen in the mixture is adsorbed to saturation by the sample, resulting in an adsorption signal, and then desorbs from the liquid nitrogen environment. During the heating process, the adsorbed nitrogen begins to desorb to *, resulting in a desorption signal.

BET specific surface area meter
1： Product principle
Specific surface area analyzerThe continuous flow method (standard comparison method) proposed by Nelsen and Eggertsen was used as the measurement method. Under the action of low-temperature liquid nitrogen, a helium nitrogen mixture was continuously introduced into the sample tube. The nitrogen in the mixture began to adsorb to saturation by the sample, resulting in an adsorption signal, and then detached from the liquid nitrogen environment. During the heating process, the adsorbed nitrogen began to desorb to *, resulting in a desorption signal.

lHigh sensitivity, no gas dry burning and no damage;
lGas purification, stable flow rate, and ensuring testing accuracy;
lNo need to start preheating, fully automatic intelligent operation.
lEach analysis station corresponds to an independent flow control system
L has * gas path detection function.
Fully automatic testing mode, no need for manual operation. No need for manual supervision.
High performance TCD with more stable results.
3： Product Upgrade
Improved the gas path structure of the instrument and added gas path detection function.
Two additional air flow stabilizing devices have been added,Further ensure the stability of the equipment.
Three adopts four independent control channels, which can simultaneously control the airflow status of each channel, complementing interference and influence.
Improved software interface optimization, making it easy for operators to understand at a glance.
