Product Info

  • Details
  • Specifications

BELCAT II is the analyzer of choice for catalyst researchers and enables comprehensive catalyst evaluation by using the following techniques:

  • Pulse chemisorption
  • Temperature programmed desorption (TPD)
  • Temperature programmed reduction (TPR)
  • Temperature programmed oxidation (TPO)
  • Temperature programmed reaction (TPReaction)
  • BET single point measurement


  • Acidity study of cracking catalyst by ammonia or pyridine TPD
  • Basicity study of solid base catalyst
  • Metal dispersion rate evaluation of exhaust gas catalyst / fuel cell electrode catalyst
  • Determination of optimal preparation conditions of catalyst
  • Catalytic reaction study



  • Affordable price
  • Small foot print
  • Precise gas control by three high performance mass flow controllers
  • Precise automatic gas injection system for calibration
  • The pulse loop with temperature/pressure sensor enables the highly reproducible result
  • A variety of options to fulfill the customers' demand
  • With the standard gas mixing equipment, mixed gases (H2/Ar, O2/He, etc...) are not necessary
