Overview
The specific surface area and pore size analyzer features a multi module collaborative design for core performance. It adopts an intelligent integrated structure and integrates degassing and analysis modules to achieve synchronous operation of sample pretreatment and testing, reducing space occupation and improving detection efficiency. The independent gas path system and vacuum solenoid valve technology can achieve a vacuum degree of up to 10 ⁻⁸ Torr, ensuring a pollution-free testing environment. The three analysis stations have parallel processing functions and support the specific surface area (≥ 0.0001 m/g), pore size distribution (0.35-500 nm), porosity and true density of solid powders, fibers and other materials.
Product Details
Specific surface area and pore size analyzerAdopting an integrated design, that is, the degassing module is integrated into the instrument host, reducing a lot of space for the laboratory; At the same time, its degassing module and analysis module are independent of each other, with independent gas path system, detection system, and vacuum system, which can operate simultaneously without affecting each other, improving the detection speed of quality control analysis; Each analysis port is equipped with an independent pressure sensor to ensure data consistency and stability; An independent saturation vapor pressure detection system monitors the saturation pressure in real-time during the analysis process to ensure the accuracy of the data.
Specific surface area and pore size analyzer
Having one sample analysis port and one degassing port, it can simultaneously analyze one P0 test position (the sample analysis station can be 1, 2, 3, 4, 6, 8. The degassing position can be 2, 4).
The degassing and analysis positions are designed in an integrated manner, and have independent vacuum and gas circuit systems.
Uneven and vulnerable soft heating package, composite material heating furnace with linearly adjustable heating rate, high temperature control accuracy, and anti scald design.
Each analysis port is equipped with an independent inlet pressure sensor, ensuring high data consistency.
Introduce dead volume dynamic calibration technology to address the impact of liquid nitrogen volatilization on volume quantification.
The pneumatic control system applies vacuum pumping dynamic speed regulation technology (I-PID).
