Typical application

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. Proper carbon black or white carbon black on the specific surface area can be selected according to the tire or rubber purposes.

Nanometer Materials

Surface area and porosity of nanometer materials has decisive influence on their hydrogen storage, oxygen storage and special substance adsorption, such as the typical CNT (carbon nanotube).

Electronic Field

The inner filling materials of capacitor require high specific surface, so as to produce capacitor of smaller volume but larger capacity. Likewise, in the design of ordinary batteries, it is also necessary to consider the material's specific surface area, in order 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 furthermore, 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, the combustion rate is controlled by the material's specific surface. If the speed is too high, it may be more dangerous; or if the speed is too low, it may cause failure and inaccuracy.

Active Carbon

Besides 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.

Vacuum System

FINESORB-3020 analyzer employs 2 independent vacuum systems, one for analysis station and the other for degassing station, which allows degassing and analyzing at the same time, and avoids the delay and error caused by using one vacuum system. In addition, the independent systems completely eliminate the effects of gas purity between degassing and analysis.

Intelligent Degassing Station System

The degassing station can choose the proper degassing temperature and degassing time depending on the sample conditions. The degassing processed information can be saved as files for future analysis on the effects of sample degassing conditions for the results, so as to ensure the testing conditions' traceability.

Volumetric Tank and Gas Feeding System

Volumetric tank adopts an integrative design to avoid temperature deviation. Due to its compact structure, the integrated volumetric tank has smaller dead volume, and the measured results are more accurate. Installation and settlement of structural sensor of integrated design are more rational and easy for further expansion. The volumetric tank is demarcated accurately. The volume repeatability error of gas feeding can be ignored

Multi-Gas Support

FINESORB-3020 analyzer supports to use N, Ar, Kr, Co, Co, H and He as adsorbate. The instrument internally supports analysis of multiple data models, so that more types of sample can be analyzed.

Multiple Cold Bath Support

FINESORB-3020 analyzer supports to use liquid nitrogen, liquid oxygen, liquid argon and other cold baths. The instrument internally supports adsorption models under multiple cold bath conditions, which is easy for analyzing multiple types of sample.

Temperature Maintaining System

Dewar flask with longer heat insulation time, sealing soft cover and equipped with heat preserving case, the temperature of the sample pipe can be maintained. The instrument is also optionally equipped with a siphon system which will automatically add liquid nitrogen when the liquid level temperature drops.

High-precision Sensor

The instrument is equipped with a built in high-precision resistance sensor and a Pirani-gauge sensor, which can detect pressure from 1*10^-6 Pa to 2*10⁵ Pa, so that the mesopore and micropore adsorption and desorption can be analyzed completely.

Cold Trap Filtering Device

FINESORB-3020 analyzer is equipped with a cold trap filtering device. It uses liquid nitrogen or the mixed solution of liquid nitrogen and isopropanol as cold trap pool, so that the vacuum degree can be enhanced.

Other Accessories

Off-line Degassing Station

This equipment can make preparation for specific surface and pore capacity analysis for multiple sets of sample. Usually the pollutants such as the steam and adsorbed gas are removed from the sample surface or pore by using following gas or vacuum in combination of heating device. The accuracy of the specific surface and pore capacity analysis data largely depends on the clean degree of the sample surface.

The common preprocessing equipments can use inert gases like helium, nitrogen and argon or vacuum atmosphere. Off-line degassing station can support 6 paths of sample degassing.

LN2 Storage and Transmission

Liquid nitrogen requires special containers to store. The common capacity of containers for laboratory use has several sizes ranging from 10 L to 100L. Customers can choose the liquid nitrogen tank with proper capacity according to the laboratory’s use frequency,

Liquid Nitrogen Siphon Equipment

Depending on the laboratory condition, customers can choose manual or automatic siphon equipments to facilitate adding liquid nitrogen from the liquid nitrogen tank to the Dewar flask. This equipment is optional, for concrete choices, please contact 4008261126.

Reference materials

Usually reference materials are required for test to verify the instrument’s performance in china, GBW (E) 130275-GWE (E) 130279 standard substances are used for verifying the specific surface. Internationally, standard substances of NIST are used.

During the actual usage, some substances which have been tested by different authorities will be used for reference, such as white carbon black, molecule sieve, crystal ball and active carbon, etc.

Vacuum Pump

During usage, the instrument requires equipping sliding vane rotary vacuum pump and molecular pump and molecule pump, The vacuum pump performance is directly related to the vacuum pump. During purchase, pump is an item of the list; customers can choose the appropriate pump according to their needs. In addition, different pump models are chosen for degassing station and analysis station. Please call 4008261126

Ultrahigh vacuum

Take the optional micro molecular pump as a secondary pump, which can increase the vacuum system to high vacuum. Equipped with Pirani vacuum gauge, the micropore measurement can be performed or the krypton can be used for specific surface analysis.
