The Autopore IV 9500 series of mercury porosimeters from Micromeritics enable the user to calculate numerous sample properties.
These include pore size distributions, total pore volume, total pore surface area, median pore diameter and sample densities (bulk and skeletal).
The Autopore IV 9500 characterises 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 instrument is available in 33,000lb/in2 and 60,000lb/in2 models with either two low- and one high-pressure ports or four low- and two high-pressure ports.
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.
The instrument has the capability to measure pore diameters from 0.003 to ~1,000um.
It comes with an enhanced data reduction package, which includes tortuosity, permeability, compressibility, pore-throat ratio, fractal dimension, Mayer-Stowe particle size, and more.
It operates in scanning and time - or rate - equilibrated modes.
It collects extremely high-resolution data, better than 0.1uL for mercury intrusion and extrusion volumes.
