The ChemiSorb Auto provides core chemisorption capabilities at a price point accessible to academic and industrial labs alike.

Chemisorption Catalyst Characterization

Chemisorption is a surface-specific process where adsorbate molecules undergo chemical reactions with solid surfaces, forming strong, often irreversible bonds through electron sharing. This high-energy interaction is essential for catalyst characterization, offering insights into activation temperatures, available surface metal, site strength, and performance across redox cycles. Available tests:
1

温度プログラム低減(TPR)

  • Catalyst activation behavior
  • Max reduction rate
  • Quantitative hydrogen consumption
2
Temperature Programmed Oxidation (TPO)
  • Evaluate catalyst regeneration
  • Characterize carbon deposits
  • Study redox properties
3
温度プログラム脱離 (TPD)
  • Characterize acid and base sites
  • アイソステリック吸着熱
  • Evaluate binding affinity
4
パルス化学吸着
  • Number of active sites
  • Metal dispersion
  • Active metallic surface area
  • Crystallite size

Software / Intuitive MicroActive

Move quickly from data to decision

Rapidly transition from experimental data to material characteristics with Micromeritics’ own MicroActive data analysis software.
Get all the answers you need with:

  • Interactive peak analysis including: limit selection, baseline definition, integration, and deconvolution
  • Built-in analysis models for pulse chemisorption, % dispersion, metal surface area, crystallite size, first order kinetics, heat of desorption, activation energy, BET surface area, and more
  • 質量分析データのシームレスな統合
  • 詳細で設定可能なグラフィカルレポート
  • Automatic file exporting for data management

Program what you envision, visualize what you have programmed

The new MicroActive method editor features an intuitive
process illustration that shows the programmed state of the
instrument at every step of the method so you can
see that your method matches your vision.

Automatic Gas Calibration

Determining the active gas concentration in the mixture with an automatic calibration procedure is a breeze. ChemiSorb Auto will automatically mix the inert gas feed from the carrier MFC with the active gas feed from the loop MFC via the patented blend valve. This is done in a stepwise function across a range of concentrations, allowing the user to apply the saved calibration to a variety of sample data sets. Linear and polynomial fits are applied to the curve with correlation coefficients >0.995.
