Analyte Adsorption and Distribution

Analyte Adsorption and Distribution

In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and solvents...

Adsorption Isotherms II

Adsorption Isotherms II

Brunauer, Emmett, and Teller (BET) introduced a theory in 1938 that modified Langmuir's assumptions to explain multilayer physical adsorption. This theory is applicable to Type II isotherms and provides a more realistic picture of adsorption processes. The BET theory assumes a uniform solid surface with localized adsorption sites, where adsorption at one site doesn't affect adsorption at neighboring sites. This theory also allows for the possibility of additional molecules being adsorbed on top...

Analysis of phase transitions within the model.
Identification of an order parameter to quantify the transition.
Investigation of fractal dimensions for particle distributions.

Main Results:

A distinct clustering transition was identified, separating weakly and strongly correlated particle distributions.
The transition leads to the formation of localized fractal clusters in the strongly correlated phase.
The fractal nature of particle distributions was analyzed for both phases.

Conclusions:

The proposed model successfully describes particle clustering and a phase transition.
The findings offer insights into the fundamental mechanisms driving aggregation and pattern formation.
The model's relevance extends to diverse fields including materials science, ecology, and urban studies.
