Mercury intrusion – determine the porosity of your product

Mercury intrusion is a powerful and fast characterization technique to study the porosity of materials

We can help you examine your product’s properties in terms of size, distribution of sizes, surface area and volume of pores. These are crucial properties determining the performance of your material for your specific application.

Mercury is a non-wetting liquid with high surface tension, making it the ideal to study porosity properties as function of an external pressure. As a result, high-pressure mercury intrusion is the most complete pore analysis characterization method, covering a very large range of porosities, from nanometers to several hundreds of microns accomplished in a single measurement.

The technique is especially useful for

  • Catalysis, as the catalytic activity is related to porosity 
  • Oil recovery, where the geologic conditions of porosity are key parameters
  • Electronics, such as battery plates or electrodes
  • Materials resistance, such as corrosion rate studies

We can help you with

  • Pore size distribution
  • Total pore volume
  • Total pore surface area
  • Median pore diameter
  • Sample densities (bulk and apparent)

Combined analysis methods give the best results

At the department for Nano Production and Micro Analysis at Danish Technological Institute, we have more than 25 years of experience solving characterization tasks for our customers.

We often combine results from several separate types of state of art characterization equipment and can offer you a design of experiments that suits your materials requirements, in a short delivery time.
