AutoChem II 2920 Chemisorption Analyzer, Micromeritics Instrument Corporation (CAT#: STEM-LE-0441-LC)

The fully automatic AutoChem II 2920 is designed for the research of chemical adsorption and temperature-programmed reactions. This single instrument can provide you with valuable information about the physical characteristics of catalysts, catalyst supports or other materials.

Temperature Control: -100C to 1100C (with CryoCooler), [RT + 0C] to 1100C (without CryoCooler)
Gases: H2, CO, O2, N2O, NH3 vapors such as pyridine, water, etc.; He, Ar, and other gases
Measures: Catalytic Properties: Percent of metal dispersion, Active metal surface area, Acid strength, Surface acidity, Distribution of strength of active sites, BET surface area, pulse chemisorption, temperature-programmed reduction (TPR), desorption (TPD), oxidation (TPO).

Powerful Windows operation and data reduction software
Three gas ports (preparation, carrier gas and analysis) contain four gas inlets, so that four gas sequential experiments can be performed
Four high-precision, independently calibrated mass flow controllers ensure extremely accurate programmable gas control
Using the CryoCooler option, the analysis temperature can vary from -120°C to 1100°C
Provide graphical reports for BET surface area, pulse chemical adsorption, adsorption heat, etc. In addition, AutoChem II also contains a full-featured peak editor and integrated software package. This easy-to-use software package provides a quick way to evaluate common temperature programming and dynamic adsorption data.
