ASAP 2050XP

Micromeritics ASAP® 2050 Xtended Pressure Sorption Analyzer is an easy-to-use instrument capable of collecting high-resolution, high-pressure adsorptive isotherms from vacuum to 10 atmospheres. While retaining many design elements of the popular ASAP 2020, the ASAP 2050 offers an extended range of capabilities that enables the instrument to obtain data in an elevated-pressure environment. The instrument also allows the user to collect traditional isotherms for determining surface area and porosity

Typical ASAP® 2050 Applications
The performance of the metal hydride is characterized by its hydrogen storage capacity (adsorption) and subsequent release (desorption) of hydrogen. The adsorption capacity of alkaline-exchanged zeolites is a key parameter for the design and optimization of pressure swing adsorption processes. The active surface area and porous structure of catalysts have a great influence on production rates. The ASAP 2050 is also useful in generating surface area and porosity data for materials such as nanotubes, activated carbons, and ceramics.

Features

Standard ASAP Features

  • Two independent vacuum systems allowing simultaneous automated preparation of two samples and analysis of another
  • A highly flexible and interactive reporting system that includes an extremely versatile graphic user interface allowing custom presentation of results
Additional ASAP 2050 Features

Analysis System

  • An optional chiller Dewar and recirculating bath allow the ASAP 2050 to be operated indefinitely - the instrument also supports the use of a standard Dewar with cryogen (typically liquid nitrogen or argon) that will provide at least 50 hours of unattended analysis without refilling the Dewar
  • Straight-walled, stainless-steel sample tubes are capable of safe operation up to 150 psia
  • Rapid collection of non-monotonic isotherms with standard isotherm cycling software
  • Special degas heating mantles can be used to prepare samples in situ on the analysis port prior to analysis
Degas System
  • Temperatures at each degas port, and the rate of temperature change, can be set and monitored individually from a few degrees above ambient to 450 oC
  • A user specified pressure setting protects the sample from steaming or damage during sample preparation
ASAP 2050 Standard 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.
  • Repetitive Isotherm Cycling
  • DFT (Density Functional Theory) / NLDFT (Non Linear 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

A Note About 32- and 64-Bit Windows and Micromeritics' Software
Micromeritics products are designed to operate in most Microsoft Windows  environments. However, more current versions of Microsoft Windows, specifically the 64-bit version of Windows 7, lack some of the services once offered by Microsoft. Because of this, Micromeritics applications will not operate with 64-bit operating systems. Micromeritics software applications are directly compatible with 32-bit version operating systems only. In cases where a 64-bit operating system may be corporate-required or essential for running other software programs, Virtual PC software and a 32-bit operating system should be installed on the host computer (64 bit) as a guest operating system. This will allow proper installation and operation of the Micromeritics application.
