Introduction: SSA-4000 is a multi-analysis station automatic physical adsorption analyzer for mesoporous and macroporous nanomaterials; it has advanced technology, excellent quality, more comprehensive theoretical models, and has ultra-high stability and repeatability , which can also be used for simple analysis of microporous samples. The SSA-4000 specific surface area and pore size analyzer adopts an integrated design, that is, the degassing module is integrated on the instrument host, which reduces 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 system The detection system and the vacuum system can run at the same time without affecting each other, improving the detection speed of quality control analysis; each analysis port is equipped with an independent pressure sensor to ensure the consistency and stability of the data; the independent saturated vapor pressure detection system, in the analysis The saturation pressure is monitored in real time during the process to ensure the accuracy of the data. Features: 1. Analyze the host Has three sample analysis ports and three degassing ports for simultaneous analysis Integrated design of degassing position and analysis position, and has a completely independent vacuum system and gas circuit system The degassing position adopts a more advanced composite material heating furnace to replace the non-uniform and fragile soft heating package. The heating rate of the composite material heating furnace is linearly adjustable, the temperature control accuracy is high, and it has an anti-scalding design. Each analysis port is equipped with an independent imported pressure sensor, with high data consistency Introduce dead volume dynamic calibration technology to solve the effect of liquid nitrogen volatilization on volume quantification The pneumatic control system applies the vacuum pumping dynamic speed regulation technology (I-PID) Optional embedded isothermal jacket for gas isothermal adsorption test at 0℃-60℃ 2. Durable high performance furnace Independent research and development and manufacturing, advanced technology, high temperature control accuracy, can be used for a long time at high temperature Isothermal heating body is adopted, the temperature rise is stable, the constant temperature area is wide, and there is no heating dead angle. The furnace body is equipped with a protective interlayer to avoid touching and scalding The furnace body is not fixedly installed, which is convenient for maintenance and replacement 3. Simple and clear control software One-key start, automatic software control, automatic data saving Real-time display of equipment operating status, convenient for later maintenance Real-time display of the pressure and vacuum degree of each analysis port to better grasp the status of the equipment analysis port Each analysis port can independently set the analysis method (specific surface analyzer/full hole analysis) Each analysis port can independently set the gas injection volume, which is more conducive to the test of different types of samples technical parameter: Test function: adsorption and desorption isotherms, BET/Langmuir specific surface area, BJH Pore Volume / Pore Area / Total Pore Volume / Total Pore Area Analysis, Test range: specific surface area ≥ 0.01m2/g, pore size analysis 0.35nm-500nm Test accuracy: ±1% (≤1m2/g sample: ±1.5%) Analysis station: 3 sample analysis ports, 1 P0 real-time test position Dewar volume: 3.5L Degassing station: 3-station sample preparation station, with independent temperature control system and vacuum system, the upper temperature limit is 400 °C, equipped with an independent mechanical pump, the degassing station can work at the same time as the analysis station, and the degassing time and temperature can be set on the host interface and change Pressure detection system: each analysis port is equipped with an independent imported pressure sensor, the software terminal can view the pressure value of each position in real time, and the saturated vapor pressure test position is equipped with an independent pressure sensor to collect the saturated vapor pressure in real time Vacuum system: The main engine is equipped with a two-stage rotary vane mechanical pump, and the ultimate vacuum is 10-2Pa Partial pressure range: P/P0 10-7-0.995 Air circuit control system: applying vacuum pumping dynamic speed regulation technology (I-PID) and manifold air circuit
