TP-5079, a dynamic adsorption instrument, is one important tool for property research on catalysts surface. Many characterizations can be performed on it including temperature programmed reduction (TPR), temperature programmed oxidation (TPO), temperature programmed desorption (TPD), hydrogen-oxygen titration (HOT), temperature programmed surface reaction (TPSR) and so on. Thus, the redox and acid-base nature and adsorption-desorption properties of probe molecules can be obtained. Besides, the instrument has extended applications in the nature analysis of minerals and soils, hydrogen/oxygen storage measurement and selective adsorbent adsorption. Data can be conveniently processed on its own special data processing software and of course it can be conveniently exported to other professional software (eg, Excel and origin) for further processing. In addition, the instrument can be optionally connected with mass analyzer for dynamic research on the catalyst surface. 　Fully automated anal
