Asap 2420
Manufactured by Micromeritics
Sourced in United States, United Kingdom
The ASAP 2420 is a surface area and porosity analyzer designed to measure the specific surface area and pore size distribution of solid materials using the principles of gas adsorption. The instrument utilizes high-precision pressure and temperature sensors to accurately determine the volume of gas adsorbed on the sample surface at various relative pressures. This data is then used to calculate the specific surface area and pore size distribution of the material.

Surface area and pore textural characteristics of the conductive agents used in this work were obtained from the N2 adsorption isotherms for pressures up to 1 bar measured by a volumetric method using a Micromeritics ASAP 2420 instrument at 77 K (liquid nitrogen bath). Samples were evacuated and activated at 200°C under dynamic vacuum at 10−6 torr for 12 hours to remove any residual solvent and measure the sample mass precisely. Gas adsorption measurements were performed using ultrahigh-purity nitrogen. Brunauer-Emmett-Teller surface area and pore-size distribution data were calculated from the N2 adsorption isotherms based on the density functional theory model in the software provided within the Micromeritics ASAP 2420 instrument.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
