Enter a number in the text box to indicate the intraparticle porosity of the stationary phase.
The intraparticle porosity is the fraction of the total volume of the stationary phase particles that contains eluent. It is defined by the following equation:
where
εi = intraparticle porosity
Vi = volume of eluent within the stationary phase particles
Vp = total volume of the stationary phase (including the eluent within the particles)
The intraparticle porosity is usually around 0.4
