Who should attend?
Analysts who characterize solid, granular, and powdered materials primarily for the determination of pore characteristics and additionally to determine other physical characteristics such as bulk and skeletal density, particle size distribution, compressibility, and permeability.
Curriculum
- Theory of pore size determination by mercury intrusion
- Other extractable information about the material under study
- Inspection of the intrusion and extrusion plots to evaluate data quality
- Typical causes of poor data quality
- Limitations of the technique
Background
Mercury intrusion porosimetry is one of only a few analytical techniques that permit an analyst to acquire data over such a wide dynamic range using a single theoretical model. Mercury porosimetry routinely is applied over a pore diameter range from 0.003 μm to >360 μm. Not only is mercury porosimetry applicable over a wide range of pore sizes, but distinctive attributes of the fundamental data it produces (volume of mercury intruded as a function of applied pressure) is indicative of various other physical characteristics of the sample material.
Understanding how mercury behaves under specific conditions provides insight into exactly how a mercury porosimeter probes the pore structure of a material. This knowledge allows one to better understand what mercury intrusion and extrusion data mean in relation to the sample under test and understand the data outside the bounds of the theoretical model. One can also make an educated comparison between similar data obtained using other measurement techniques and theoretical models.
