Features

Multi-function

Essential analysis for catalyst evaluation such as TPD, TPReduction, TPO, Metal dispersion, BET 1 point method, Pulse adsorption can all be carried out by one unit.

High sensitivity

Equipped with high sensitivity 4 element TCD.

Upgrade

Simultaneous analysis of gases such as TPReacton is possible with the Q-mass option.

High reproducibility

Our unique TPD sample cell does not allow re-adsorption, and also catalyst temperature can be measured directly.  Therefore, highly reproducible data can be obtained.

High efficiency

Pretreatment and adsorption measurement can be carried out simultaneously with BET 1 point method, and thus the throughput is doubled.

Sophisticated

There is no dead volume due to the usage of 3-way and 4-way switching valve so that gases can be purged easily.

High accuracy

Purge type 6-way switching valve is used that prevents contamination with outside air.

Wide meas. range

Wide adsorption amount range can be measured as a result of simple one-touch switching of TCD sensitivity and the 2 different volume of pulse injection loop
