ASAP 2020 Plus Accelerated Surface Area and Porosimetry System

  • The ASAP 2020 Plus is a high-resolution surface area and porosity analyzer
  • It is perfect for research, development, and quality control purposes
  • It is an independent preparation and analysis instrument in a single cabinet 

The surface area, pore volume, and pore size of powders and porous materials can be measured using the high-resolution ASAP 2020 Plus adsorption analyzer. Standard methods or user-customized procedures can be utilized to characterize catalysts, absorbents, zeolites, active pharmaceutical ingredients (API), metal-organic frameworks (MOFs), excipients, and a wide range of porous and non-porous materials.

The ASAP 2020 Plus offers exceptional accuracy, resolution, and data reduction and is well suited for gas adsorption analysis of mesoporous (2 to 50 nm) and microporous (0.35 to 2 nm) materials.  To increase the ASAP 2020 Plus physisorption’s analytical range, a vapor sorption option can be introduced.

The ASAP 2020 plus can now be utilized for physical and chemical adsorption to characterize the active surface and texture of catalysts, catalyst supports, sensors, and a wide range of other materials, thanks to the addition of a chemisorption option.

Features and Benefits

Design Versatility

  • Two separate vacuum systems enable concurrent preparation of two samples while analyzing another. This boosts staff productivity and return on investment.
  • The innovative Isothermal Jacket Cold Zone Control and continuous saturation pressure (Po) monitoring provide a stable thermal environment for saturation pressure and adsorption. Invest time in outcomes rather than managing temperature fluctuations.
  • Numerous extra attachments are available for the ASAP 2020 Plus for customization to the user's analytical needs.

Advanced Capabilities Through Optional Configurations

The ASAP 2020 Plus can be designed to meet individual requirements, with the option of upgrading at a later time as analytical needs change, increasing the value of this instrument and the investment.

Users can choose between low surface area, heated vapor, and micropore capabilities. When working with hostile vapors, add a cryostat or external detector, or modify the machine for increased chemical resistance. The ASAP 2020 Plus is a single instrument designed to meet almost all surface characterization requirements in the laboratory. 

The addition of a chemisorption option broadens the ASAP 2020 plus's application range to include physical and chemical adsorption for assessing the texture and active surface of catalysts, catalyst supports, sensors, and several other materials.

Unique and Innovative Isothermal Jacket Cold Zone Control

Isothermal jackets are guaranteed for the life of the instrument and maintain a consistent thermal profile over the whole length of the sample and saturation pressure (Po) tubes.

Application

Pharmaceuticals

The purification, processing, blending, tableting, and packaging of drugs, as well as their usable shelf life, dissolution rate, and bio-availability, are significantly influenced by surface area and porosity.

Ceramics

Surface area and porosity impact greenware curing and bonding, as well as the strength, texture, appearance, and density of finished goods. Shrinkage, crazing, and crawling are all affected by the surface area of glazes and glass frits.

Adsorbents

Understanding surface area, total pore volume, and pore size distribution is critical for industrial adsorbent quality management and separation process development. The surface area and porosity of an adsorbent influence its selectivity.

Activated Carbons

To achieve gasoline vapor recovery in vehicles, solvent recovery in painting processes, or pollution controls in wastewater management, surface area, and porosity must be optimized within tight limits.

Carbon Black

The surface area of carbon blacks utilized in tire manufacture is associated with tire wear lifespan, traction, and performance.

Fuel Cells

To achieve optimal power density, fuel cell electrodes must have a large surface area with regulated porosity.

Catalysts

The pore structure and active surface area of catalysts impact production rates. By restricting the pore size, only molecules of the required size can enter and depart, resulting in a selective catalyst that produces predominantly the intended product.

Paints and Coatings

The gloss, texture, color, color saturation, brightness, solids content, and film adhesion qualities of a pigment or filler are all affected by its surface area. In offset printing, the porosity of a print medium coating impacts blistering, ink receptivity, and ink holdout.

Projectile Propellent

Propeller burn rate is a function of surface area; too high a rate can be harmful, while too low a rate might cause malfunction and inaccuracy.

Medical Implants

Controlling the porosity of artificial bone allows it to mimic actual bone and be accepted by the body, allowing tissue to develop around it.

Electronics

Manufacturers of super-capacitors can reduce the utilization of expensive raw materials while offering greater exposed surface area for charge storage by using high surface area materials with properly constructed pore networks.

Cosmetics

Cosmetic manufacturers frequently employ surface area as a predictor of particle size when the agglomeration tendencies of fine powders make evaluation with a particle-sizing device problematic.

Aerospace

The weight and functionality of heat shields and insulating materials are influenced by their surface area and porosity.

Geoscience

Porosity is correlated with both the volume of fluid that a structure can hold and the amount of work necessary to extract it. It is therefore significant in the fields of groundwater hydrology and petroleum exploration.

Nanotubes

The ability of a material to hold hydrogen is predicted using the surface area of nanotubes and microporosity.

Software

Software and Reporting Versatility

The user-friendly ASAP 2020 software uses a Windows® interface that includes Wizards and applications that assist in organizing, launching, and managing the analysis. Raw data can be gathered, organized, reduced, archived, and stored with standardized sample data and analytical settings for convenient access in the future.

Completed reports can be sent by data transfer routes, paper, or screens. Features include configurable reports, editable and scalable graphs, and cut-and-paste graphics. Extra capacities consist of:

  • Degas temperature profiles and treatment duration data are incorporated with the sample file for future reference and SOP compliance verification.
  • The Instrument Schematic screen shows the current operational condition of the instrument, including the real-time isotherm, and allows the operator to take manual control of the instrument if required.
  • Overlays can be used for comparison. 
  • Exportable data tables allow users to combine and compare data from several sources in a single spreadsheet file. 
  • Three forms of gas dosing processes offer excellent options for ensuring maximum speed and accuracy for samples with widely varying isotherm shapes.
  • The proprietary Smart Dosing™ procedure detects the sample’s ability to absorb gas and modifies the adsorptive dosages accordingly. This helps to avoid overdosing the sample and distorting porosity data.
  • Through a data file or table, the user can input any reference isotherm into the system. This isotherm can be used to calculate thickness for t-Plots, s (Alpha-S) plots, and BJH pore size distribution instead of using the pre-programmed thickness curves. For comparisons, it is possible to overlay additional plotted data with the reference isotherm.

Analyses and Reports

Potent data reduction software is included with the ASAP 2020 to offer a range of easy-to-interpret report options. This gives users a great deal of freedom in the selection of analysis constants to best fit their specific application. 

With the capacity to conduct adsorption and desorption studies throughout the whole pressure range, or collect data over a predetermined portion of the pressure range, all ASAP models can provide comprehensive surface area and porosity data.
