Dynamic Specific Surface Area Analyzer

Product Description

Measuring Principle 

Dynamic adsorption uses the relative pressure between carrier gas and adsorbed gas to achieve the method of BET measurement, by the concentration detector to characterize the volume of adsorption. The same as static adsorption method, it needs to do degassing before measurement under the circumstance of nitrogen temperature.

Functions

1. Isotherm (Adsorption and Desorption)

2.BET Specific Surface Area (Single-point BET and Multi-point BET)

3. Langmuir Specific Surface Area

4.  Porosity Distribution (Differential Distribution and Accumulative Distribution）

5. Total Pore Volume and Average Porosity

6. Can be extended to achieve TPD, TPR and TP

Features

1. Tester for aperture distribution under atmospheric pressure improves by the flow control system. 

2.Flow control system with high precision ensures the accuracy of relative partial pressure. 

3. TCD control system of 4 rhenium tungsten with high precision includes module for constant temperature and flow.

4.  It can be connected with multi-function chemisorption instrument to achieve comprehensive analysis from BET to TPD, TPR and TPO.

5. Both isobaric interval model and optimization model are optional, can take care of measuring precision and speed.

6.The software records the data for test process and is up to the standard of *1 CFR.

7. The controlling system with precision level guarantees the minimum dead volume.

8.With strong function, the software can monitor the test process at real-time, switch among various kinds of measuring models, derive the data to EXCEL, print and print preview.
