Fast and Accurate Porosimety Analyses AutoPore IV Series Automated Mercury Porosimeters

The term “porosimetry” is often used toinclude the measurements of pore size, volume, distribution, density, and otherporosity-related characteristics of a material. Porosity is especially important in under- standing the formation, structure, and potential use of many substances. The porosity of a material affects its physicalproperties and, subsequently, its behavior inits surrounding environment. The adsorption and permeability, strength, density, and other factors influenced by a substance’s porosity determine the manner and fashionin which it can be appropriately used. The mercury porosimetry analysis techniqueis based on the intrusion of mercury into a porous structure under stringently controlledpressures. Besides offering speed, accuracy,and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as poresize distributions, total pore volume, totalpore surface area, median pore diameter, and sample densities (bulk and skeletal).The AutoPore IV Series MercuryPorosimeters can determine a broader poresize distribution (0.003 to 360 micrometers) more quickly and accurately than other methods. These instruments are enhanced with features that enable them to moreaccurately gather the data needed to charac-terize the porous structure of solid materials. They also offer new data reduction and reporting choices that provide more infor- mation about pore geometry and the fluidtransport characteristics of the material.

Wide Variety ofBenefits Four Models

AutoPore IV 9510: 1 high-pressure (60,000psia maximum pressure) and 2 low-pressure analysis ports AutoPore IV 9520: 2 high-pressure (60,000psia maximum pressure) and 4 low-pressure analysis ports •Controlled pressure can increase inincrements as fine as 0.05 psia from 0.2 to 50 psia. This allows detailed data to becollected in the macropore region.•A quick-scan mode allows a continuouspressure increase approximating equilib- rium and providing faster screening. The high repeatability and reproducibility ofthis method by the AutoPore means thatsmall, but significant, differences between samples will be detected. You can use this technique to screen a sample for conformity to specification becauserepeatability remains high.•High-resolution (sub-microliter) measurement of intrusion/extrusion volumes produces extraordinary precision allowing the development of tighter samplespecifications, improved productionprocesses, and high-quality research data.•A choice of correction routine for base-line (automatic, differential, or manual) produces greater accuracy by correctingfor compressibility and thermal effectscaused by high pressure.•Choice of pressure ramping methods letsyou choose the scanning technique forhigh-speed or on-demand results, or equilibration techniques for more accurate results with greater detail.•The instrument allows the user toprogram data collection using a minimumnumber of data points.However, during intervals of unex- pectedly large amounts of intrusion, the AutoPore will automatically collect additional data points.•Choose between three data plot routines constructed of collected data points, a continuous curve plotted from interpolated data, or a combination of points and curves.•A variety of pore volume, pore area, and pore size plots is available as well as the ability to calculate total intrusion volume, total pore (surface) area, median pore diameter, average porediameter, bulk density, and apparent(skeletal) density. The AutoPore IV Series is available in four models to best match the needs of individual quality assurance and research labs. AutoPore IV 9500: 1 high-pressure (33,000psia maximum pressure) and 2 low-pressure analysis ports AutoPore IV 9505: 2 high-pressure (33,000psia maximum pressure) and 4 low-pressure analysis ports
