ASAP 2050 XP Software Features and Reports

The easy-to-use ASAP 2050 software utilizes a Windows interface that includes Wizards and applications to help plan, launch, and control the analysis. You can collect, organize, archive and reduce raw data, and store standardized sample information and analysis conditions for easy access during later applications. Finished reports may be generated to screen, paper, or data transfer channels. Features include cut-and-paste graphics, scalable-and-editable graphs, and customizable reports.

Additional capabilities include:

  • Degas temperature profiles and treatment time data are integrated with the sample file for future reference and verification of SOP compliance.

  • The Instrument Schematic screen displays the instrument’s current operating status, including the real-time isotherm, and allows the operator to assume manual control of the instrument if desired.

  • One computer can control two Micromeritics ASAP analyzers of the same or different model making efficient use of valuable lab space. Other types of Micromeritics instruments can also be connected.

  • Up to nine graphs can be overlaid for easy comparison of different samples or for comparison of different data reduction techniques applied to the same sample.
  • Exportable data tables provide for merging and comparing data from other sources in a unified single spreadsheet file.

  • Three modes of gas dosing routines provide effective choices to ensure maximum speed with full accuracy for samples with widely differing isotherm shapes.

  • The patented Smart Dosing™ routine actually learns about the sample’s potential to adsorb gas and adjusts the adsorptive doses accordingly. This helps prevent over-dosing the sample and obscuring porosity information.

  • The user can enter any reference isotherm into the system by way of a data file or table. This isotherm can be used in place of the pre-programmed thickness curves when calculating thickness for t-Plots, Alpha-S plots, and BJH pore size distribution. The reference isotherm can also be overlaid with other plotted data for comparisons.

Analyses and Reports

The ASAP 2050 includes powerful data reduction software to provide a variety of easy-to-interpret report options. This allows tremendous flexibility in the selection of analysis constants to best fit your specific application. All ASAP models have the capability to collect data over a prescribed segment of the pressure range, or to perform adsorption and desorption analyses over the entire pressure range, providing extensive surface area and porosity information. The ASAP 2050 is a versatile adsorption instrument. In addition to collecting adsorption isotherms up to 150 psia, traditional isotherms may be collected with nitrogen; BET surface area and BJH pore size distributions are easily determined.

The ASAP 2050 model includes:

  • Repetitive Isotherm Cycling
  • DFT (Density Functional Theory)
  • Single- and Multipoint BET (Brunauer, Emmett, and Teller) surface area
  • Langmuir surface area
  • Temkin and Freundlich isotherm analyses
  • Pore volume and pore area distributions in the mesopore and macropore ranges by the BJH (Barrett, Joyner, and Halenda) method using a variety of thickness equations including user-defined, standard isotherm
  • Pore volume and total pore volume in a user-defined pore size range
  • F-Ratio plots that illustrate the difference between theoretical and experimental isotherm data
  • Heat of Adsorption
