Autopore V series

AutoPore V – Features

Optional Advantages:

• Ability to measure pore diameters from 0.003 to 1100 µm*
• Controlled pressure can increase in increments as fine as 0.05 psi from 0.2 to 50 psia. This allows detailed data to be collected in the macropore region
• High-resolution (sub-microliter) measurement of intrusion/extrusion volumes produces extraordinary precision allowing the Development of tighter sample specifications, improved production processes, and high-quality research data
• Operates in scanning and time- or rate-of-intrusion equilibrated modes
• Real-time diagnostics provide knowledge of an issue before it becomes critical or impairs your analytical results
• Collects extremely high-resolution data; better than 0.1 µL for mercury intrusion and extrusion volume
• Improved linear motion for high-pressure chamber closure

Typical Applications

Pharmaceuticals:

Porosity and surface area play major roles in the purification, processing, blending, tableting, and packaging of pharmaceutical products as well as a drug’s useful shelf life, its dissolution rate, and bio-availability.

Ceramics:

Pore area and porosity affect the curing and bonding of greenware and influence strength, texture, appearance, and density of finished goods

Adsorbents:

Knowledge of pore area, total pore volume, and pore size distribution is important for quality control of industrial adsorbents and in the development of separation processes. Porosity and surface area characteristics determine the selectivity of an adsorbent

Catalyst:

The active surface area and pore structure of catalysts influence production rates. Limiting the pore size allows only molecules of desired sizes to enter and exit, creating a selective catalyst that will produce primarily the desired product.

Aerospace:

Surface area and porosity of heat shields and insulating materials affect weight and function

Fuel Cells:

Fuel cell electrodes require controlled porosity with high surface area to produce adequate power density

Geoscience:

Porosity is important in groundwater hydrology and petroleum exploration because it relates to the quantity of fluid that a structure can contain as well as how much effort will be required to extract it

Filtration:

Pore size, pore volume, pore shape, and pore tortuosity are of interest to filter manufacturers. Often, pore shape has a more direct effect upon filtration than pore size because it strongly correlates with filtration performance and fouling.

Construction Materials:

Diffusion, permeability, and capillary flow play important roles in the degradation processes in concrete, cement, and other construction materials.

Paper:

The porosity of print media coating is important in offset printing where it affects blistering, ink receptivity, and ink holdout

MicroActive Software for AutoPore V

Intelligent, Intuitive, Interactive:

MicroActive software greatly improves the functionality, convenience, diagnostics, and data interpretation that establish the new standard for high-performance results in mercury porosimetry.

Method Wizard:

Build a method through an interactive step-by-step script. Eases method creation and new user introduction to the operation of the AutoPore V.

Mercury Density Calculation:

Unlike competitive systems that use mercury density at ambient temperature only, the AutoPore V automatically measures the actual mercury temperature for accurate density calculations under operation conditions.

User-Defined Reports and Report Options:

You can quickly create custom advanced reports to meet your specific needs using Python scripting. New report options permit automatic report conversion to PDF or spreadsheet formats.

Post-Analysis Parameter Change:

Allows analysis parameters (stem volume, maximum head pressure, pen constant) to be changed or corrected post analysis, eliminating re-running samples due to error.

Enhanced Penetrometer Calibration:

Simplifies penetrometer calibration through automated calculations either volumetrically or gravimetrically.

Diagnostic Dashboard:

Real-time monitoring of critical system components for preventative maintenance and trouble shooting.

Overlay Multiple Runs and Gas Adsorption Data:

MicroActive for AutoPore V provides the ability to overlay up to 20 runs. Included is the option to import pore size distributions from gas adsorption isotherms to provide analysis data in the micro to macropore range in a single report.

Intelligent Data Reporting:

Warnings are supplied automatically when suspect data are collected.

Variety of Available Plots:

Pore volume, pore area, and pore size plots are available as well as the ability to calculate total intrusion volume, total pore (surface) area, median pore diameters, average pore diameters, bulk or envelope density, and apparent (skeletal) density.

Reverberi Method Data Reduction:

Receive information on the distribution of pore shape. The method yields a three-dimensional array of cavity size and throat size vs. volume.
