4 Pressure sensor Surface Area & Pore Size Analyzer Surface Area Analyzer

Features

TMAX-1001 Surface Area And Porosimetry Analyzer accords with the international standards ISO9277, ISO 15901 and National standard Gb-119587. It tests desorption process in the principle of static capacity measurement tested through static gas balance and pressure tested. They are tested in the temperature of liquid nitrogen. The gas of known quantity is filled into the sample tube and the pressure is to fall, then  the 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

TMAX-1001 Surface Area And Porosimetry 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. Designed for the study of micropores, this instrument is equipped with diffusion pumps (or molecular pumps) and is a research-grade instrument designed to keep the system in a 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.
