ASAP 2020 PLUS Surface Area and Porosity analysis system for solid materials

ASAP 2020 PLUS, Micromeritics (USA) is an automated system for analyzing the surface area and studying the porous structure of materials using physical sorption methods. Complete analysis of micro- and mesopores, their size distribution and determination of surface area. Pore diameter measurement range from 0.35 to 500 nm.

Accurate measurement of surface area and porosity is very important for determining the performance and quality of various hard materials, as well as for studying and modifying their properties. ASAP 2020 PLUS solids surface area and porosity analysis system combines versatility and versatility in one convenient benchtop instrument. Management is carried out by means of a computer with software in the WINDOWS environment, providing a fully automatic analysis. Multi-tasking software allows to manage the analysis process, data collection saving the results and issuing reports without interrupting work in other programs (word processors, etc.). ASAP 2020 PLUS can be used both in research laboratories and in production, ensuring the accuracy and reproducibility of analysis results.

Configurations:

Standard ASAP 2020 PLUS system (base model ASAP 2020N) can be modified for other surface surveys. All additional features can be integrated into the standard instrument and do not require separate instruments.

HighVac Option - High vacuum option (model ASAP 2020HV)
In addition to the standard version of the device, it is equipped with a 10 mm Hg sensor and a high vacuum turbomolecular pump. Allows to conduct research at low pressure and high resolution required for the analysis of small specific surfaces using krypton as adsorbate gas.

Micropore Option - micropore analysis option (Model ASAP 2020MP)
High vacuum system (with HighVac Option) can be upgraded to a micropore analysis system. To do this, a 1 mm Hg sensor and micropore analysis software are added. In this case, the system becomes capable of analyzing, in addition to mesopores (from 2 to 500 nm), the size distribution of micropores in the range from 0.35 to 2 nm, providing in addition a choice of different models for processing the results.

Chemisorption Option - Option for chemisorption studies (models ASAP 2020C or ASAP 2020C-MP) A system with the HighVac or Micropore Option can be upgraded to a catalyzed chemisorption system. ASAP 2020C-MP model allows both physical sorption (including micropores) and chemisorption analysis.

Enhanced Chemical Resistance Option - Option for the use of corrosive gases.
ASAP 2020 stainless steel internal piping system, combined with chemically resistant Kalrez gaskets, allows the use of aggressive gases or vapors for analysis. This option is ideal for experiments with unsaturated hydrocarbons such as benzene or toluene.

Vapor Adsorption Option - Option for the adsorption of water vapor or volatile liquids.
Allows the use of water vapor or other liquids as an adsorbate gas.

Additional features:

DFT Plus
DFT (Density Functional Theory) method uses an experimental isotherm to determine microporosity and mesoporosity as a continuous distribution of pore volume relative to pore size. DFT Plus software for WINDOWS allows you to calculate the distribution of pore volume, surface energy and pore size. Special libraries are available for various pore shapes.

Repetitive Isotherm Cycling Option
This option allows to run up to 500 adsorption/desorption cycles within the specified range of the experimental isotherm section.

Rate of Adsorption Option
This option allows to measure the rate at which various gases are adsorbed on the surface of porous materials at selected pressures. This is useful for evaluating the ability of a surface to adsorb and retain various gases.

Data Master
Software package that allows to process the results of experiments without the device or on another computer (not connected to the device).

Application:

Fully automatic ASAP 2020 PLUS system is used to analyze the surface area and porosity of a variety of materials. Here are just a few examples:

● Catalysts - the active surface area and pore space structure of catalysts directly affect the rate of chemical processes and the yield of the finished product. Limiting the pore size of the catalyst allows molecules of only a certain size to penetrate into the catalyst, which determines its selectivity and makes it possible to obtain only the necessary products. Chemisorption studies evaluate the performance of a catalyst over time to determine when it should be replaced or regenerated, its quality, activity, and so on.

● Ceramics - Information about surface area and porosity allows you to influence the production of ceramics and, ultimately, to obtain a product of a certain texture, strength and density.

● Pharmaceuticals ﾖ Surface area and porosity play a major role in the purification, manufacturing, blending, tableting and packaging of pharmaceuticals. The shelf life and dissolution rate (i.e. how quickly the drug will be absorbed by a person) also directly depend on the surface and porosity of the material.

● Carbon Black - Tire manufacturers know that the surface area of carbon black (as a filler) affects tire life, traction, and other tire characteristics.

● Dyes - The surface area of a pigment or filler affects the texture, color, saturation, gloss, brightness, and adhesion of the resulting coating.

● Activated carbons - Surface area and porosity must be optimized within a very narrow range for the use of activated carbons in the automotive industry, in the production of water filters, etc.

● Medical implants - The surface area and porosity of materials used in medical implants affect the adhesion of materials to bone and other tissues of the body

● Electronics - Production of compact, miniature capacitors requires the development of materials with controlled surface area and porosity.

● Cosmetics ﾖ Surface area allows particle size estimation of cosmetic materials when conventional particle size analysis methods fail (e.g. due to agglomeration)

● Nanotubes - The surface area and microporosity of nanotubes makes it possible to evaluate the capacity of the resulting material for storing hydrogen

● Fuel Cells - Fuel cell electrodes need to have a large surface area with controlled porosity for optimum power.

● Aerospace - The surface area and porosity of refractory screens and insulating materials affect both their weight and functionality.
