Asap 2420 analyzer
The ASAP 2420 is a surface area and porosity analyzer manufactured by Micromeritics. It utilizes the static volumetric technique to measure the surface area and pore size distribution of a wide range of materials. The instrument is capable of determining the physical characteristics of solids, powders, and porous materials.

Characterization of Lindlar Catalyst
of metallic palladium (4–5% according to the producer) deposed
on calcium carbonate deactivated with lead oxide (PbO) was purchased
from Sigma-Aldrich. The catalyst is in reduced form (Pd0) and is maintained in this state thanks to the reductive atmosphere
in the reactor.
The catalyst is characterized by ICP–AES
analysis and BET and BJH methods for surface area and porosity.
Elementary analysis of the Lindlar catalyst was determined by a VARIAN
720-ES ICP–AES. The solid sample was attacked with a strong
acid and then diluted with deionized water, before being nebulized
into an analytical nebulizer onto the plasma flame.
The sample
(150 mg, 50 μm < dp < 100
μm) was degassed in the degassing unit of a Micromeritics ASAP
2420 analyzer at 100 °C for 8 h with ramp program of 10 °C/min.
In the same apparatus, N2 adsorption and desorption isotherms
at −196 °C were recorded and specific surface area (SBET) and volume (VBJHdes and VBJHads) were calculated. For the
average pore size of the sample, both the BJH distribution and the
average value assuming homogeneous cylindrical pores are reported.

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.
