Instrument Introduction
SA-2000PW multi-station weight method vapor sorption analyzer is research-grade analytical instrument, by microbalance weighing certain relative partial pressure of desorbed sample before and after absorbing the change in weight was measured adsorption-desorption amount of the sample for a particular steam, gas.
Compared to the volumetric method, without using any compromise approximation, there is no zone distribution, gas and other non-ideal sources of error correction, so especially in higher precision and accuracy for testing steam gas, and make up for volumetric method deficiencies, which can't Real-time test isobaric adsorption rate  and cannot accurately describe the adsorption kinetics in materials;
SA-2000PW multi-station weight method vapor sorption analyzer can test materials for water vapor adsorption of organic vapors and gases, the adsorption rate and other parameters; gravimetric method in a vacuum vapor sorption apparatus, is the world's first multi-station instrument, supports 1-8 analysis station simultaneous analysis, applied for the adsorption properties of a variety of materials research and development of research institutes and business users, because of its unique advantages, gravimetric method instruments are widely used in high-end laboratories around the world .
