BELPREP VAC II

BELCAT II is fully-automated catalyst analyzer that was developed building on the experience and technology of the well-established and popular BELCAT series.

BELCAT II is the catalyst analyzer of choice for researchers in the according fields 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
