Introduction:Micromeritics' AutoPore IV 9500 characterizes a material’s porosity by applying various levels of pressure to a sample immersed in mercury. The pressure required to intrude mercury into the sample’s pores is inversely proportional to the size of the pores. This is called mercury porosimetry, or often, “mercury intrusion.” The AutoPore IV series provides high-quality analysis data and comes with enhanced data reduction and reporting packages, faster pressure ramp rates, a more flexible and controllable vacuum system, and a redesign of both the low-and high-pressure generation systems.

Features:

The term "porosimetry" is often used to include the measurements of pore size, volume, distribution, density, and other porosity-related characteristics of a material. Porosity is especially important in understanding the formation, structure, and potential use of many substances. The porosity of a material affects its physical properties and, subsequently, its behavior in its surrounding environment. The adsorption and permeability, strength, density, and other factors influenced by a substance’s porosity determine the manner and fashion in which it can be appropriately used.

The mercury porosimetry analysis technique is based on the intrusion of mercury into a porous structure under stringently controlled pressures. Besides offering speed, accuracy, and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter, and sample densities (bulk and skeletal).

The AutoPore IV Series Mercury Porosimeters can determine a broader pore size distribution (0.003 to 1100 micrometers) more quickly and accurately than other methods. These instruments are enhanced with features that enable them to more accurately gather the data needed to characterize the porous structure of solid materials. They also offer new data reduction and reporting choices that provide more information about pore geometry and the fluid transport characteristics of the material.
