The AMI Micro-300 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. Every analysis station has its own dedicated dosing manifold for optimal analysis duration. 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. The three analysis stations can also be used for in-situ sample preparation to avoid sample contamination. It can effectively take microporous analysis of microporous materials such as molecular sieve, catalyst, activated carbon, and other microporous materials.
