The new Micromeritics ASAP 2460 surface area and porosimetry analyser from Particle & Surface Sciences incorporates a unique expandable system designed for upgradeable high-performance and high sample throughput.
 
This versatile surface characterization instrument can be configured as a two-, four-, or six-station bench top system depending on the user’s throughput needs.
 
The base ASAP 2460 is a two-port master control unit; for additional throughput, one can connect two-port auxiliary units to the master unit expanding the system to either a four-port or six-port analyser. Enhanced software capabilities, data reduction features and instrument monitoring are some of the other product highlights.
 
Optimised for walk-up sample screening, all analysis ports can be operated independently and concurrently, allowing the user to load and unload samples at any time regardless of the preparation or analysis stage. A new analysis can begin as soon as another is finished.

Long-duration dewars and isothermal jackets assure a stable thermal profile along the length of both the sample and the saturation pressure (P0) tubes throughout lengthy analyses. The P0 value may be entered or measured either continuously or at selected intervals. An analysis of up to 60 hours can be performed without refilling the dewar, allowing unattended analysis of high-resolution adsorption/desorption isotherms.
 
Servo control for dosing and evacuation provides a higher degree of gas management and speeds the collection of data points. The user can attach up to five different nonreactive adsorptives, plus an additional gas for free space to the analyser simultaneously. Each analysis port can accept a range of sample tube sizes. Low surface area krypton and micropore options are available.
 
Micromeritics ASAP 2460 surface area and porosimetry analyser comes with intuitive MicroActive software that 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 modelling for BET, t-plot, Langmuir, DFT interpretation, and new advanced NLDFT methods. MicroActive data analysis software also includes a powerful utility that allows overlays of mercury porosimetry pore size distribution with a pore size distribution calculated from gas adsorption isotherms. An interface to the Python programming language allows users to develop extensions to the standard ASAP 2460 report library.
 
An innovative dashboard monitors and provides convenient access to real-time instrument performance indicators and maintenance scheduling information, enabling the user to maintain the instrument in peak operating condition with real-time analysis views.
