Product Description

Surface Area and Pore Size Analyzer Pore Size Measurement Instrument Surface Area Analyzer 
1.Product introduction
The GA 100 Series can accurately produce surface area and pore size results of powder materials. According to the different test functions, this series of instruments are divided into three types, there are A, B, and C, the C type is configured with 1 torr or 0.1 torr high-sensitive pressure sensors and turbo molecular pump with ultimate pressure of 10¯8 Pa, it can effectively take microporous analysis of microporous materials such as molecular sieve, catalyst, activated carbon, and other microporous materials.

2.Features

• Test Module
• Internal temperature of test module can be controlled through Real-time monitoring, ensuring accuracy of adsorption detection.
• Saturated Vapor Pressure P0
• Using independent P0 pressure sensor for P0
  value by inching test, guarantees the reliability of experimental data. Atmospheric pressure input method to determine P0 also be selected.
  Pressure Sensor
  Mico 100Cwith 1torr (selectable 0.1torr) makes the partial pressure of P/P0up to 10-7 -10-8(N2/77K) in the physical adsorption analysis.
• Vacuum System
• It's a multi-channel, adjustable, andparallel vacuum system. Vacuum degree of this system can be controlled in segments.
  This design prevents the sample from being pumped into analyzer. Meanwhile, a delicate part was designed for ensuring cleanliness of vacuum system, minimizing dust pollution.
• Sample Preparation System
• In addition to two pretreatment stations, the other two analysis stations can be used in preparing samples.There is no interference between pretreatment stations and analysis .
  stations. Degas temperature can be set individuallyand controlled from ambient to 400 oC.
• old Free Space
• Cold free space can be corrected by Helium automatically, ensuring accuracy of test results. This calibration method is suitable for testing of any
  powderor particle material.
• Control of Liquid Nitrogen level
• Using High volume (3L) Dewar flasks and working with the seal cover assure a constant thermal profile along the length of sample tubes and P0 tubes throughout testing process.
  Turbo Molecular Pump
  Molecular pump is a standard configuration part on the Micro 100C. The ultimate pressure is up to 10-8 Pa, providing a strong support for micropore analysis in the ultra-low pressure. The smallest micro-pore diameter can be tested is 0.35 nm.
• Sample Preparation System
• In addition to two pretreatment stations, the other two analysis stations can be used in preparing samples. There is no interference between pretreatment stations and analysis stations.
  Degas temperature can be set individually and controlled from ambient to 400 degree centigrade
• Micropore Distribution
• Accurately apply the HK method, SF method and other micropore analysis model, the aperture deviation of micropore is less than 0.02 nm.
• Surface Area and Pore Size Analyzer Pore Size Measurement Instrument Surface Area Analyzer 
• 3. PAS Control and Analysis Software
• PAS Software is intelligent software in operation control, data acquisition, calculation and analysis and report generation on the Windows platform. This software can communicate with the host through the LAN port and remotely control many instruments at the same time.
• PAS Software adopts a unique intake control method, the pressure in adsorption and desorption process is optimally set in six- stage; this flexible design is helpful for improving test efficiency.
• Changes of the pressure and temperature inside the manifold can be observed directly in the test interface which is convenient for sample test and instrument maintenance.
• Current state of analyzer can be intuitively understood with the indicator light and event bar.
• Each adsorption equilibrium process is dynamically displayed on the test interface. Adsorption characteristics of the sample can be easily understood.
