ADSORPTION ANALYSIS [3 records]

Record 1 2013-08-16

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Mathematics, Physics and Natural Sciences
  • Electronics and Informatics
  • Medicine and Health
DEF

The diameter calculated from a ratio of particle volume to specific surface area adsorption.

OBS

This determination is applicable for non-porous spherical particles and often carried out by the BET [Brunauer-Emmett-Teller] method.

OBS

The BET [Brunauer-Emmett-Teller] method aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of a material.

OBS

specific surface area mean diameter: term and definition standardized by the International Organization for Standardization (ISO).

DEF

Diamètre calculé à partir du rapport entre le volume d'une particule et l'aire de surface spécifique déterminée par adsorption.

OBS

Cette détermination est applicable aux particules sphériques non poreuses et elle est souvent réalisée par la méthode BET [Brunauer, Emmett et Teller].

OBS

La méthode BET [Brunauer, Emmett et Teller] permet d’expliquer l’adsorption physique des molécules de gaz sur une surface solide et permet la mesure de la surface spécifique.

OBS

diamètre moyen de l'aire de surface spécifique : terme et définition normalisés par l'Organisation internationale de normalisation (ISO).

CONT

Although real-life gas chromatography analysis is a complex process depending on numerous factors such as molecular volume, chemical and physical properties, the form of the analyzed molecules, the temperature of the process, the adsorption abilities, other properties of the matrix, etc., the separation for many compounds depends on differences in boiling points.
