ASAP 2460 & 2425

Analytical Versatility With Superior Throughput

Surface area and porosity are important physical properties that influence the quality and utility of many materials and products. Therefore it is critically important that these characteristics be accurately determined and controlled. Likewise, knowledge of surface area and especially porosity often are important properties in understanding the formation, structure, and potential application of many natural materials.

High Performance and High Sample Throughput The automated Micromeritics® ASAP® 2425 surface area and porosimetry system is designed to help busy laboratories expand their workflow while providing highly accurate and precise surface area and porosimetry data. High performance, versatile analysis, and sample preparation systems are included in the same instrument.

Analysis System

• With six independently operated analysis ports, a new analysis can begin as soon as another is finished.
  This provides an important advantage over many multiport instruments that require all samples to be
  prepared or analyzed at the same time.
• Long-duration Dewars and Micromeritics Isothermal Jackets1 assure a constant thermal profile along
  the length of both the sample and saturation pressure (Po) tubes throughout extended analyses.
  The Po value may be entered, or measured either continuously or at selected intervals.
• The high-capacity Dewar also allows unattended analysis of high-resolution adsorption/desorption
  isotherms that take much longer to complete because the system must equilibrate at each data point.
• BET surface area analyses utilizing six parallel runs can be achieved in as little as 1 hour.
• A low surface area option that uses krypton as an adsorptive to measure total surface areas of 0.5 m2 or less is available. This option utilizes five of the six available ports. It also features a turbomolecular drag pump, which provides the high vacuum required for krypton analyses, and a 10 mmHg pressure transducer, which allows accurate, repeatable pressure resolution.
• 直观的Micromeritics MicroActive软件将用户定义的报告与可以交互评估等温线数据的能力相结合。用户选择的数据范围通过图形接口允许直接建模，用于BET，T-Plot，Langmuir，DFT解释和新的高级NLDFT方法。
• Up to five different nonreactive adsorptives, plus an additional gas for free space, can be attached to the analyzer simultaneously.
• 伺服压力控制在分析过程中调节剂量和疏散，以减少分析时间。

Sample Preparation System

• The ASAP 2425 system includes twelve automatically controlled sample preparation ports that operate
  independently. Samples may be added or removed from degas ports without disturbing the treatment of
  other samples undergoing preparation.
• The sample preparation system is fully automated with controlled heating time profiles. Temperature
  and ramp rate can be set and monitored individually and controlled from a few degrees above ambient
  to 450 °C. The temperature hold period may extend past the point when evacuation is completed.
• A programmable pressure threshold can suspend the temperature ramp if the outgassing pressure exceeds the limit specified, preventing destructive steaming or other undesired reactions with residual gasses and vapors.

Low Surface Area Measurement (Krypton) and Micropore Options

In addition to the standard ASAP 2425, low surface area krypton and micropore models are available.

Low surface area (krypton) model includes the addition of a 10 mmHg transducer and permits accurate
measurement of very low surface area materials (< 1 m2/g).

The micropore model includes the addition of a 1 mmHg transducer which extends the low pressure measurement capabilities and allows enhanced performance for characterizing microporous materials. The transducer also increases pressure resolution in the range necessary for micropore analysis.

Superior Data Presentation Capability

创新的微型软件
微粒学的创新MicroActive软件ows users to interactively evaluate isotherm data. Users can
轻松地包括or exclude data, fitting the desired range of experimentally acquired data points using interactive,
movable calculation bars. Isotherms can be viewed on either a linear or logarithmic scale.

Data Reduction Benefits

• Interaction with adsorption data is direct. By simply moving the calculation bars, the user is immediately updated with new textual properties.
• Interactive data manipulation minimizes the use of dialog boxes and tunneling of dialogs to specify
  calculation parameters.
• Ability to overlay files (up to 25) including mercury intrusion data with a file add-and-subtract feature.
• 游览器通过图形的数据范围terface allow direct modeling for BET, t-Plot, Langmuir,
  DFT interpretation, and much more.
• Report Options editor allows the user to define reports with on-screen previews. Information from each
  report can be included in a concise summary, as well as in a tabular and graphical information pane.
