Features
 
Data Reduction: high-precision PρT gas density calculation model eliminates measurement errors caused by non-ideality gas state, can increase analysis accuracy
Thermostatic System: analysis modules designed with thermostatic system can control temperature up and down easily, also hold modules stay at the best temperature(25℃) which can restrain transducer reading’s temperature drift and keep system temperature uniformity; System can maintain temperature at a fixed value for some fixed-temperature-required samples
Control System: programmable logic controller (PLC) system obtains high integration and strong anti-interference, software operated fully automated analysis enables freely choose of multi experiment modes
Analysis Management: programmable built-in system, touch screen, USB type external keyboard and mouse, operated by connecting to computer is available
Manifolds System: patented V-Sorb assembling-installed manifolds system can improve sealing performance and reduce dead space largely, enhance system temperature’s uniformity and anti-interference ability, all lead to a high accuracy and repeatability data
Splash-proof Measures: installed with a detachable filter in sample cell’s bottom, can prevent samples be suctioned into manifolds; inputting gas from cavity bottom can avoid samples splash and software controlled H-Sorb two-stage-stepping mode further ends splash happening
Sample Container: 50mm (diameter) and 180ml (500ml is available) big cylinder sample cell is convenient for samples filling; Exclusive G-DenGyc filling technology supports to choose different volumetric aluminum blocks to fill cell instead change other sizes cells according to samples’ volume, this innovative method realizes minimal free space in cells and improve experiment accuracy
 
 
Application
 
Apply to research and quality control for below materials: ceramic, catalysts, filter medium, nuclear fuel, oil & chemical industry, soil, fertilizer, carbon black, hard coke, fiber, minerals, pharmacy, cosmetics, cement, powdered foodstuff, desiccant (drying agent), powdered metal, ion exchange resin, silicon gel, alumina, titanium dioxide, solid foam etc.
 
Carbon Black / White Carbon Black
Tire and rubber manufacturers find that the specific surface area of carbon black has great influences on the service life, friction and rubber performance. The carbon black or white carbon black with proper specific surface area can be selected according to the tire or rubber purposes.
Nanometer Materials
Surface area and porosity of nanometer materials are decisive for their hydrogen storage, oxygen storage and special substance adsorption, such as the typical CNT (carbon nano tube).
Electric Field
The inner filling materials of capacitor require high specific surface, so as to produce capacitor with smaller volume but larger capacity. Likewise, in the design of ordinary batteries, it is also necessary to consider the material's specific surface area, so as to gain smaller volume and larger storage power.
New Energy Battery
New energy battery is the hot field for research currently. It controls the proper stored energy density by controlling the material's specific surface.
Paints and Coatings
Filler surface area of paints and coatings affects the smoothness, texture, color, color saturation, brightness, solid content and film's adhesion property. The porosity can control the application program's performance, such as liquidity, curing time and coating thickness, etc.
Catalyst
Catalyst's active specific surface area and pore structure have great influence on the conversion ratio. Choose the aperture size to filter or transit some substance selectively, so as to create a selective catalyst, and in turn, produce the desired products.
Automobile Exhaust  
Purification of resultants of the automobile exhaust requires special catalyst material. The exhaust purification using transition metal is of important practical significance and economic value. The specific surface and porosity decide the efficiency, service life and economical efficiency of the exhaust conversion device.
Combustion Control
In the research and development of rocket propellant and explosive, it is necessary to control the combustion rate by controlling the material's specific surface. If the speed is too high, it may be more dangerous; while if the speed is too low, it may cause failure and inaccuracy.
Active Carbon
Besides serving as an extremely great carrier material, the active carbon is also an ideal filtering material. The filtering effects can be controlled by controlling the active carbon's specific surface and porosity. It has important application in the gas and liquid purification fields.
Pharmaceuticals 
The tablet dissolution rate and medical effect action time can be controlled by rationally distributing the effective constituents of the medicines on the filler with certain specific surface area and porosity.
