What is a Bet Surface Area and Pore Size Analyzer

The BET surface area and pore size analyzer, also known as BET Surface Area Analyzer . It is an advanced instrument used to measure the specific surface area and pore characteristics of a material. It works on the principle of Brunauer-Emmett-Teller (BET) theory, which states that the adsorption of gas molecules onto a solid surface can be used to determine its surface area. The analyzer operates by introducing a known amount of gas into a sample chamber, where it gets adsorbed onto the material's surface. By effectively measuring the amount of gas adsorbed at various pressures, the BET equation can be applied to calculate the sample's surface area. Additionally, this sophisticated instrument also allows for determining pore size distribution by characterizing desorption isotherms using models such as Barrett-Joyner-Halenda (BJH) or t-plot methods. Researchers and scientists extensively utilize this analyzer in fields like material science, petroleum refining, pharmaceuticals, and catalyst development for comprehensively understanding porous materials' properties. With its precise measurements and reliable results, the BET surface area and pore size analyzer is an invaluable tool in quantitative analysis within various research capacities.

BET Surface Area and Pore Size Analyzer

Brief Introduction

Rise Series Automatic specific BET surface area and Pore size distribution Analyzer accord with the international standards ISO9277, ISO 15901, and National standard GB-119587. It tests the desorption process in the principle of static capacity measurement tested through static gas balance and pressure tested. They are tested at the temperature of liquid nitrogen. The gas of known quantity is filled into the sample tube and the pressure is to fall, then Moore's quality of adsorbed gas is calculated. With calculated balance adsorption quantity and theoretical model, the instrument evaluates the parameters such as single-point, multipoint  BET specific surface area, Langmuir specific surface area of the samples; BJH mesoporous, macroporous area, area distribution; t-plot microporous and surface areas, Dubinin Astakhov microporous distribution,  Hovath-Kawazoe microporous distribution; DFT and MC aperture distribution model.


Guarantee for Trustworthy Tested Data

Reasonable connection of pipes, capability of s vacuum pumping, precision and sensitivity of sensors, automation of the instrument and numbers of the digital models for the different samples.


Modular Gas pipes Design

Rise-1010 Automatic specific surface area and Pore size distribution Analyzer accords with the most developed design ideas, designed with special modular stainless steel vacuum pipes . It is leak-proof and pollution-free. It is high vacuum and avoids leakage due to excessive pipe connections. It is specially-designed research instrument for the micropores study, with diffusion pump to keep the system high vacuum.

Constant temperature

Dewar flasks is self-developed with special internal structure, store the liquid nitrogen for more than 10 days. The liquid nitrogen is almost free of losses during the test so that the temperature of the tested samples is constant and that the Dewar flasks are protected as they are fragile and unfavorable for movement.


High-precision sensors

Several high-precision sensors and 22-bit AD converters ensure the precision of the specific surface area and aperture.


Developed theoretical model

With DFT and MC aperture distribution models, it is developed in the world, and is the Number One of the specific surface area and Pore size distribution Analyzers in China.


Automatic operation

Adsorption and desorption processes are automatically controlled by computers and free of manual operation.


Applied range

 It is applied in study and test of all kinds of materials such as zeolite, carbon material, molecular sieve, silicic acid anhydride, aluminum oxide,soil, clay, catalytic agent, organic metal  compound cageconstruction.
