Description 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.
