Description

Device consists of three automatic mercury intrusion porosimeters (two low pressure stations plus one high pressure station) achieving a maximum pressure of 33,000 psia for measurements in the range from over 950 micron to 0.0064 micron pore diameter. It is possible to measure two different samples using low pressure station simultaneously. The relationship between the applied pressure and the pore diameter into which mercury will intrude is given by the Washburn equation.

Specification

Pore diameters for different pressure ranges: for 0 - 50 psia: 950 - 4.26 µm (accuracy ± 0.11 % fso), resolution 0.000763 psia; for 0 - 1500 psia:10.66 - 0.142 µm (accuracy ± 0.11 % fso), resolution 0.0229 psia; for 0 - Maximum psia 10.66 - 0.0064 µm, resolution 0.511 psia. Compressed dry gas regulated to 60 psig, cryogen Hg vapour cold trap, vacuum pump. Dimensions: 51 cm/65cm/78cm Weight: 179 kg Electrical: 100-240 AC; 50/60 Hz; 1000 W

Services

Analysis of pores in the sample (up to 1 mm), including cumulative/differential pore volume (or surface area) versus pressure or pore diameter, pore number fraction versus pressure or pore diameter, particle size distribution, permeability, percent porosity.
