ASAP 2020 Plus Physisorption from Micromeritics

The ASAP 2020 Plus is a top-tier adsorption analyzer that measures surface area, pore size, and volume in powders and porous materials.

High-resolution surface area and porosity analyzer

Independent preparation and analysis instrument in a single cabinet

Ideal for research, development, and quality control applications

The ASAP 2020 Plus is adaptable, allowing standard methods or personalized protocols to assess adsorbents, catalysts, zeolites, MOFs, APIs, excipients, and a broad range of porous and non-porous materials.

This analyzer excels in gas adsorption analysis of microporous (0.35 to 2 nm) and mesoporous (2 to 50 nm) materials, boasting unparalleled accuracy, resolution, and data handling capabilities. Moreover, an additional vapor sorption feature can be integrated to expand the physisorption analysis range of the ASAP 2020 Plus.

With the inclusion of a chemisorption option, the ASAP 2020 Plus widens its applications to encompass both physical and chemical adsorption. This functionality enables the comprehensive characterization of catalyst textures, active surfaces, catalyst supports, sensors, and various other materials.

Features and Benefits

Design Versatility

Two separate vacuum systems allow for the processing of two samples while another is analyzed. This increases employee productivity and the client's return on investment.

The innovative Isothermal Jacket Cold Zone Control and continuous saturation pressure (Po) monitoring provide a steady thermal environment for both saturation pressure and adsorption. Spend time on outcomes rather than temperature controls.

The ASAP 2020 Plus can be configured with various accessories to match individual analytical needs.

Advanced Capabilities Through Optional Configurations

The ASAP 2020 Plus can be tailored to the exact demands, with the option of upgrading later if the analytical requirements evolve, 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 an external detector or modify the machine for increased chemical resistance. The ASAP 2020 Plus allows users to use a single instrument to meet practically any surface characterization requirement in the laboratory.

Adding 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 other materials.

Unique and Innovative Isothermal Jacket Cold Zone Control

Isothermal jackets are guaranteed for the instrument's life 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 pharmaceutical goods and their usable shelf life, dissolving rate, and bioavailability are significantly influenced by surface area and porosity.

Ceramics

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

Adsorbents

Understanding surface area, total pore volume, and size distributionis 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 tuned within tight limits.

Carbon Black

The surface area of carbon blacks utilized in tire production is correlated with wear life, traction, and performance.

Fuel Cells

To achieve the best power density, fuel cell electrodes must have a large surface area and carefully regulated porosity.

Catalysts

Production rates are influenced by the catalysts' pore structure and active surface area. By restricting the pore size, only molecules with the correct sizes may enter and depart, producing a selective catalyst that predominantly produces the intended product.

Paints and Coatings

A pigment or filler’s surface area affects its gloss, texture, color saturation, brightness, solids content, and film adhesive qualities. A print medium coating’s porosity in offset printing is crucial because it influences blistering, ink receptivity, and ink holdout.

Projectile Propellent

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

Medical Implants

Artificial bone can imitate actual bone that the body will accept, allowing the tissue to develop around it by controlling its porosity.

Electronics

Super-capacitor producers can reduce the amount of expensive raw materials they require while offering greater exposed surface area for charge storage by using high surface area materials with well-thought-out pore networks.

Cosmetics

Cosmetic producers frequently utilize the surface area as a proxy for particle size when the small powders’ tendency to clump together makes using a particle-sizing device for examination challenging.

Aerospace

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

Geoscience

Porosity is related to the amount of fluid a structure can hold and the amount of work needed to extract it, making it significant in petroleum exploration and groundwater hydrology.

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 with tools and wizards to assist with organizing, starting, and managing the investigation. Raw data can be collected, arranged, reduced, archived, and stored with standardized sample data and analytical settings for convenient access in the future.

Data transfer routes, paper, or screens can send completed reports. Features include configurable reports, editable and scalable graphs, and cut-and-paste images. Additional capabilities consist of:

Degas temperature profiles and treatment duration data are saved 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 to compare.

Exportable data tables allow users to combine and compare data from several sources in a single Excel file.

Three types of gas dosing procedures give excellent options for ensuring maximum speed with full 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.

The user can enter any reference isotherm into the system via a data file or table. This isotherm can be used instead of the pre-programmed thickness curves when computing thickness for t-Plots, s (Alpha-S) plots, and BJH pore size distribution. For comparison, the reference isotherm can be superimposed with other displayed data.

Analyses and Reports

The ASAP 2020 has strong data reduction software that generates several simple-to-read report alternatives. This provides a great deal of freedom in selecting the analytical constants that are most suited to your unique application.

All ASAP models can collect data across a specified pressure range segment or perform adsorption and desorption assessments throughout the whole pressure range, giving substantial surface area and porosity information.

Single- and Multipoint BET (Brunauer, Emmett, and Teller) surface area

Langmuir surface area
