Catalyst analyzer
Overview
BELCAT-M : The BELCAT-M is the basic model of BELCAT series.
While BELCAT-M is a compact
and inexpensive instrument, a variety of measurement such as pulse chemisorption,
TPD, TPO/TPR, and single point BET can be performed. The temperature control and
data acquisition can be carried out by a high resolution interface and the measurement
software. Valves and other parts are put on the front panel in a straightforward
array and that allows intuitive and easy operation.
BELCAT-B : The BELCAT-B is a standard
model of BELCAT series.
Temperature control, data acquisition and valve operation
can be carried out automatically. Gas flow rates for carrier and pretreatment lines
are controlled accurately by MFCs. A split-type electric furnace enables quick cooling.
BELCAT-B can be customized as the customer's requirement. Measurement can be performed
easily by setting the sample cell and entering the parameters and conditions.
BELCAT-A
: The BELCAT-A is the high-end model of BELCAT series.
In addition to the function
of BELCAT-B, vapor dosing such as water, pyridine etc. is available. The vapor concentration
can be controlled with a heater. Valves and gas plumbing are placed in the temperature
controlled air oven to prevent vapors from condensation. By combining a vapor condenser
with the heater, the vapor concentration can be controlled more accurately in the
wider range.
