Surface Area and Porosimetry Analyzer: ASAP 2460
Source: Micromeritics Instrument Corporation
The ASAP 2460 Surface Area and Porosimetry Analyzer incorporates a unique expandable system designed for high performance and high sample throughput. The base ASAP 2460 is a two-port master control unit. For more throughput, additional two-port auxiliary units can be connected to the master unit expanding the system to either a four-port or six-port analyzer. The instrument also includes intuitive MicroActive software that combines user-defined reports with the ability to interactively evaluate isotherm data.
Analysis System
- All analysis ports can be operated independently and concurrently, 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 that take much longer to complete because the system must equilibrate at each data point.
- 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 control for dosing and evacuation provides a higher degree of gas management and speeds collection of data points.
- Up to five different nonreactive adsorptives, plus an additional gas for free space, can be attached to the analyzer simultaneously. Each analysis port can accept a range of sample tube sizes.
- Long-duration dewars and patented isothermal jackets assure a stable thermal profile along the length of both the sample and saturation pressure (Po ) tubes throughout lengthy analyses. The Po value can be entered, or measured either continuously or at selected intervals.
- Intuitive MicroActive software combines user-defined reports with the ability to interactively evaluate isotherm data, reducing the time required to obtain surface area and porosity results. 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.
