ChemStar TPx

Automated Flow Chemisorption Analyzer


The ChemStar is a fully automated instrument for the analysis of catalysts and other chemisorption applications. Its intuitive software interface allows the user to program and run a variety of temperature-programmed analyses as well as flow BET surface area determination and pulse titration experiments. Standard capabilities include:

  • Temperature Programmed Desorption (TPD)
  • Temperature Programmed Reduction (TPR)
  • Temperature Programmed Oxidation (TPO)
  • Temperature Programmed Reaction (TPRx)
  • Catalyst Treatment
  • Flow BET Surface Area
  • Pulse Titration
  • Pulse Calibration

Experimental conditions are fully programmable and up to 99 consecutive treatments and/or analyses can be strung together for completely unattended operation.
