Catalyst analyzer BELCATH Pulse, TPD, TPR, BET Breakthrough curve, various catalytic reactions part of VERDERiw scientific

All-in-one, fully-automatic and multi-purpose analyzer The surface properties of solid catalyst is studied in various ways. The catalytic activity of solid acid catalyst is determined by its acidity/basicity. In the supported precious metal catalysts, the dispersion rate of the supported metal, metal surface area and particle size are strongly associated with cost and performance. Adsorption kinetics and the saturated adsorption amount are keys to develop new adsorbent material. The solid catalyst reaction generally happens on its surface and the specific surface area is an important...

Applications ■Temperature-programmed desorption measurement (TPD) Known as a method to examine the chemical adsorption characteristics on the solid surface and generally represented by the spectrum with desorbed gas concentration as the Y-coordinate and temperature as the X-coordinate. By raising the sample temperature continuously and detecting the desorbed gas, desorption peak number (kind of adsorption points), desorption temperature (activation energy for desorption) and desorption amount (number of adsorption points) can be obtained. NH3-TPD as acid nature evaluation for solid acid...

Software Simple operation measurement software ●BELCATⅡ measurement view Setting up dedicated tabs for measurement items, fully automatic measurement is available only by inputting simple conditions. Measurement instruments operating status, TCD charts and temperature are displayed in real time and you can check the measurement status at a glance. Capable of automatic zero-point adjustment TCD's zero-point is automatically adjusted before measurement. Measurement is always performed at the same baseline and data comparison is easy. Continuous measurements with different carrier gases can be...

Flow pass figure The gas injection system is equipped with the gas mixing line, in addition to the carrier line, pretreatment/ pulse gas line. Gas in the mixing line can be mixed to any of the carrier lines and pretreatment/pulse gas line. Various applications are available such as TPR measurement with mixture of H2 to Ar as a carrier, injection amount control with the diluted pulse gas, etc. Also, by implementing the pretreatment line, contamination of the detector by degassing from the sample can be prevented. Stable data retrieval is available over a long period of time. （Option） BUBBLER...

Options Vapor dosing unit Consisting of an air thermostat unit, bubbling, heater and condenser. The condenser eliminates excess vapor and vapor at an accurate and stable concentration can be injected. Gas mixing unit Vapor dosing unit (Bubbler and condenser) Gas mixing unit Mixing 3 kinds or more gases. A unit can install up to 3 lines. The corrosive gas is supported. Low temperature electric furnace/ CATCryoⅡ By applying the liquid nitrogen spray, the sample temperature can be continuously controlled from -120℃. This can be utilized for the metal dispersion rate measurement for the ceria...
