Mercury intrusion is a powerful technique used to analyze the pore structure of materials, providing key information such as pore volume, pore size distribution, specific surface area, and structural characteristics. During the mercury intrusion test, two primary modes—scanning and balancing—are available to control how mercury is introduced into the sample. The AutoPore series from Micromeritics is the only commercial mercury intrusion instrument that offers both scanning and balancing modes. In balancing mode, the system can operate in either time-balanced or rate-balanced conditions, allowing for greater flexibility and accuracy in data collection.
Choosing the right mode is crucial for obtaining reliable and meaningful results. This paper provides a detailed explanation of both scanning and balancing modes, highlighting their underlying principles, operational differences, and performance characteristics. A comprehensive comparison is made between the two, along with an analysis of their respective advantages and disadvantages. This helps users make informed decisions based on their specific testing needs, ensuring optimal efficiency and precision in their experiments.
The figures included illustrate the key differences between scanning and balancing modes during mercury intrusion testing, offering visual insight into how each method affects the measurement process. Whether you are working with porous solids, catalysts, or other advanced materials, understanding these modes is essential for achieving accurate and reproducible results.
