BSD-BET400 automatic fast surface analyzer - performance parameters

Test principle:

To sample tube continuous access to a certain proportion of carrier gas (He) and adsorption gas mixed gas (N2), under the low temperature of liquid nitrogen (environment) to make the sample adsorption equilibrium, then the liquid nitrogen cup down, use hot wind to help to take off the function to make the sample tube to heat up, thereby rapidly the sample of the adsorption of N2 molecule stripping out, mixed gas concentration changes, The adsorption capacity of the sample to be measured was obtained by the concentration detector. Because the desorption peak is sharper and can be well integrated, the first choice is preferred to evaluate the initial gas adsorption amount.

(Optional) Eight-station purge pretreatment machine: Introduction to instrument functions

  For the rapid surface area analyzer of dynamic chromatography, in order to obtain the true surface area results of the material, the sample needs to be pretreated by heating and purging before the test. The dynamic chromatography full-automatic rapid surface analyzer independently developed and produced by Bester has the function of in-situ heating pretreatment. After loading the sample, you only need to install the sample tube in the test position, perform heating pretreatment first, and then directly test it. There is no need to disassemble and transfer the sample tube during the process.

However, in the case of heavy test tasks, in-situ processing will cause the instrument test position to be occupied and reduce the utilization rate of the test position. Therefore, Bester launched the BSD-AD8 purge pretreatment machine. The sample can be purged on the pretreatment machine first, and then transferred to the instrument for testing, so that the test efficiency is increased to more than twice the original.
