Broad Choice ofAnalysis and Report Parameters

Operating Software Data Reduction

The AutoPore offers various options forobtaining important sample information as quickly as possible and for presenting thedata in a format which you can design.Analysis options include choice of analysis variables, equilibration techniques, and pressure points at which data are collected. After operating conditions for the instrumenthave been chosen, they can be stored as atemplateand then reapplied to other samples,saving time and reducing the potential for human error.A selection of report options lets you cus-tomize many aspects of the data pages. You can select a specific range of data to be used in calculations; arrange columns of tabular data; select cumulative, incremental, or differential plots; scale the X-axis to display in either logarithmic or linear format for pore size; report actual or interpolated data; and select data presentation units such as psia or MPa, diameter or radius, and micrometers or Angstroms. The AutoPore IV generates tabular andgraphical reports of percentage pore volume vs. diameter, and a summary report of per-centageporosity in user-defined size ranges.The user has the ability to average several analyses and to use the ‘resulting average’ analysis as a reference with which to compare subsequent analyses. A standard, single,user-defined analysis may also be enteredand used for subsequent comparisons. SPC reports are available with collected data or user-defined parameters. In addition to the standard data reduction methods, theAutoPore IV Series also provides the following: •Mayer-Stowe Particle Size - Reports equivalent spherical size distributions•Pore Tortuosity - Characterizes the efficiency of the diffusion of fluids through a porous material•Material Compressibility - Quantifies the collapse or compression of the sample material•Pore Number Fraction - Reports the number of pores in different size classes•Pore-throat Ratio - Reports the ratio ofpore cavities to pore throats at each percent porosity filled value•Pore Fractal Dimensions - Quantifies thefractal geometry of a material•Permeability - Reports the ability of thesample to transmit fluid
The AutoPore softwareincludes a full report system for producing publication- quality graphics and user-specified reports. The pore size distribution of two aluminasamples are overlaid to provide a comparison of pore structure.
