Acquire Basic Information for Mercury Porosimetry

This script produces a graph of the intrusion and extrusion data, and a graph of the corresponding distribution of pores. It applies the mic module python calls mic.intrusion and mic.extrusion.

import mic

xdat1, ydat1 = mic.intrusion('pressure', 1)
xdat2, ydat2 = mic.extrusion('pressure', 1)
mic.graph( 'Cumulative Intrusion vs. Pressure',
           'Pressure (psi)', 'Cumulative Intrusion (mL/g)', xlinear = False )
mic.graph.add( 'Intrusion: Cycle 1', xdat1, ydat1 )
mic.graph.add( 'Extrusion: Cycle 1', xdat2, ydat2 )

xdat3, ydat3 = mic.intrusion('diameter', 1)
xdat4, ydat4 = mic.extrusion('diameter', 1)
mic.graph( 'Cumulative Intrusion vs. Diameter',
           'Diameter (Angstroms)', 'Intrusion Volume (mL/g)', xlinear = False)
mic.graph.add( 'Intrusion: Cycle 1', xdat3, ydat3 )
mic.graph.add( 'Extrusion: Cycle 1', xdat4, ydat4 )

The results are:

The following script applies the generic mic module python calls mic.sample_information and mic.report and also applies the AutoPore application specific calls mic.material_properties, and mic.mercury_properties. Three summaries are produced:
