Overview

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.

Why ASAP 2460 & 2425?

Analysis System

ASAP 2460

All analysis ports can be operated independently and consecutively, allowing the user to load and unload samples at any time, regardless of the analysis stage. A new analysis can begin as soon as another is finished.
An analysis of up to 60 hours can be performed without refilling the Dewar. This allows unattended analysis of high-resolution adsorption/desorption isotherms.
With a master unit and two auxiliary units, BET surface area analyses utilizing six parallel runs can be achieved in as little as 30 minutes.
Servo pressure control for dosing and evacuation.
Up to five different nonreactive adsorptives, plus an additional gas for free space, can be attached to the analyzer simultaneously.
Intuitive MicroActive software combines user-defined reports with the ability to interactively evaluate isotherm data. User-selectable data ranges through the graphic interface allow direct modeling for BET, t-Plot, Langmuir, DFT interpretation, and new advanced NLDFT methods.
An innovative dashboard monitors and provides convenient access to real-time instrument performance indicators and maintenance scheduling.

ASAP 2425

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.
Intuitive Micromeritics MicroActive software combines user-defined reports with the ability to interactively evaluate isotherm data. User-selectable data ranges through the graphic interface allow direct modeling for BET, t-Plot, Langmuir, DFT interpretation, and new advanced NLDFT methods.
Up to five different nonreactive adsorptives, plus an additional gas for free space, can be attached to the analyzer simultaneously.
The servo pressure control regulates dosing and evacuation during analysis to reduce analysis time.

Low Surface Area Measurement (Krypton) and Micropore Options

In addition to the standard ASAP 2425 and ASAP 240, 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.

Software

Superior Data Presentation Capability

Innovative MicroActive Software
Micromeritics’ innovative MicroActive software allows users to interactively evaluate isotherm data. Users can easily include 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.
User-selectable data ranges through the graphic interface 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.

Sample Preparation System

ASAP 2460

Micromeritics’ sample preparation devices prepare batches of samples for surface area and pore volume analysis. They combine flowing gas and/or vacuum with heat to remove atmospheric contaminants, such as water vapor and adsorbed gas, from the surface and pores of the sample.

FlowPrep 060

FlowPrep 060

The FlowPrep™ 060 applies both heat and a stream of inert gas to the sample. The heat causes contaminants to desorb from the surface and the stream of inert gas sweeps them out of the sample tube. It lets you choose the temperature, gas, and flow rate best suited for your sample material and application. Needle valves allow you to introduce the flowing gas slowly to prevent fluidization of samples.

VacPrep

VacPrep

The VacPrep™ 061 offers two methods for removing contaminants. In addition to flowing gas, it provides vacuum to prepare samples by heating and evacuation. This combination allows you to choose the preparation method that is best suited to your material or application. The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations. Needle valves are also provided allowing you to introduce the flowing gas or vacuum slowly to prevent fluidization of samples.

LN2 Transfer System

LN2 Transfer System

The Model 021 LN2 Transfer System allows you to transfer liquid nitrogen or liquid argon from a nonpressurized storage Dewar into smaller containers as needed in laboratory experiments. The system was specifically developed for conveniently filling Dewars for gas adsorption instruments and is compatible with all TriStar, 3Flex, and ASAP-series instruments. The roller base makes it easy to move the 021 System to the location where the cryogen is needed. The nozzle and insulated, flexible hose enable convenient filling and refilling of analysis Dewars. The system can hold liquid nitrogen or argon up to 30 days allowing cost-efficient use of your cryogen.

ASAP 2425

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.
