Mercury porosimeter

Contact :

Scientific correspondent : Claude Le Milbeau

Brand and model :

Autopore IV 9500 (Micromeritics)

Principle :

Micromeritics Autopore IV 9500 series characterizes the porosity of a material by applying different levels of pressure to a sample immersed in mercury. The pressure required to carry the mercury into the pores of the sample is inversely proportional to the size of the pores (Laplace’s law).

Operating pressure 0-228 MPa (i.e. pore diameters between 360 and 0.006mm). 

Objective :

characterize the porosity of a material

Treated samples :

soils, rocks

Pre-treatment :

drying of the sample at 105°C, grinding

Typical applications of the mercury porosimeter :

it can be found in the field of geosciences, ceramics, electronics, pharmaceuticals, construction materials, aerospace, etc.
