Product Overview

Micromeritics AutoPore 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.

In addition to speed, accuracy and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as pore size distributions (with volume resolution, better than 0.1 microliter), total pore volume, total pore surface area, median pore diameter and sample densities (bulk and skeletal).

Benefits

  • Ability to measure pore diameters from 0.003 to 1100* µm *Calculated with an initial filling pressure of 0.2psia (0.00128MPa)
  •  Controlled pressure can increase in increments as fine as 0.05 psia 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
  •  Improved safety features reduce the risk of mercury spills and operator exposure
  • Available with four low- and two high-pressure ports for increased sample throughput
  • Available in 33,000 psia or 60,000 psia models
  • Low-noise, high-pressure generating system
  • A quick-scan mode allows a continuous pressure increase approximating equilibrium and providing faster screening

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.

Medical Implants

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

Accessories

Penetrometer Rack

Safely store and transport penetrometers to prevent breakage and unnecessary replacement.

Mercury QuikVac

Mercury QuikVac is an excellent low-cost method for quickly containing mercury spills. The device is designed to be specifically useful in collecting those elusive mercury droplets and small mercury-contaminated particulate matter.
Mercury is collected in a 250-mL recovery vessel and a replaceable 0.3 – 0.5 micron activated carbon filter assures that the device exhausts clean, safe air.
