Record 1 2012-01-30

English

Subject field(s)
  • Analytical Chemistry
DEF

The ratio of the amount of a component adsorbed by l m² of surface area of the stationary phase to its analytical concentration in the mobile phase. This coefficient is applicable in adsorption chromatography with a well characterized adsorbent of known surface area.

OBS

In all cases, Ds must be read as D subscript s

French

Domaine(s)
  • Chimie analytique
OBS

Dans tous les cas, Ds doit se lire D indice s.

Record 2 2011-05-24

English

Subject field(s)
  • Analytical Chemistry
CONT

All chromatographic systems involving passage of a mobile liquid phase over a solid adsorbent are forms of liquid-solid chromatography. These are all classified as adsorption chromatography, and include conventional column methods, dry-column chromatography, and thin layer chromatography.

Key term(s)
  • solid-liquid chromatography

French

Domaine(s)
  • Chimie analytique
DEF

Chromatographie dans laquelle la phase mobile est un liquide et la phase stationnaire est un solide.

CONT

La chromatographie liquide-solide [...] présente l'avantage de disposer de phases stationnaires très stables, très élaborées et offertes à des prix abordables.

Spanish

Campo(s) temático(s)
  • Química analítica

Record 3 2003-11-13

English

Subject field(s)
  • Analytical Chemistry
DEF

The elapsed time between elution of two successive components, measured on the chromatogram as distance between the recorded bands.

CONT

The separation of the components, or solutes, of a sample results from differences in their rates of adsorption, solution, or reaction with the mobile and stationary phases.

PHR

Band center, phase, starch gel-electrophoretic of plasma proteins, zone center separation.

PHR

Separation efficiency.

PHR

Analytical, high-temperature separation.

French

Domaine(s)
  • Chimie analytique
CONT

Le processus de séparation chromatographique, essentiellement discontinu, consiste donc en la séparation d'un mélange complexe dilué dans un fluide en une succession de mélanges binaires soluté-fluide.

OBS

La séparation peut s'effectuer par tronçonnement de la colonne ou encore par élution.

PHR

Séparation en régime isocratique, par partage gaz-liquide, semi-préparative par recyclage, des isomères de position.

PHR

Séparation analytique.

Record 4 2003-11-06

English

Subject field(s)
  • Analytical Chemistry
CONT

Adsorption chromatography. This form of chromatography employs an adsorbent such as silica gel or alumina as a solid stationary phase, and either a liquid mobile phase... or a gas mobile phase....

OBS

Adsorption chromatography with Florisil, alumina, silica gel, and carbon as the adsorbents has been used extensively for cleanup of soil extracts prior to insecticidal determination.

French

Domaine(s)
  • Chimie analytique
DEF

Séparation principalement fondée sur les différences d'affinité des composés pour la surface du solide actif sur lequel ils sont adsorbés.

DEF

[...] type de chromatographie [...] utilisé [...] pour la séparation des substances lipophiles.

Spanish

Campo(s) temático(s)
  • Química analítica
DEF

Cromatografía basada en las diferencias entre las afinidades de adsorción de los componentes de una mezcla por la superficie de un sólido activo.

Record 5 1998-03-02

English

Subject field(s)
  • Analytical Chemistry
DEF

The ratio of the amount of a component per gram of the dry stationary phase to its analytical concentration in the mobile phase. This coefficient is applicable in ion-exchange and gel-permeation chromatography, where swelling occurs, and in adsorption chromatography with adsorbents of unknown surface area.

OBS

In all cases, Dg must be read as D subscript g.

French

Domaine(s)
  • Chimie analytique
OBS

Dans tous les cas, Dg doit se lire D indice g.

Record 6 1996-10-11

English

Subject field(s)
  • Chemistry
DEF

A situation in which molecules of adsorbate are free to move about the surface. Mobility of the adsorbate will increase with temperature and mobile adsorption may be either localized or non-localized.

French

Domaine(s)
  • Chimie
DEF

Une situation dans laquelle la substance adsorbée peut se déplacer sur la surface. La mobilité de la substance adsorbée augmentera avec la température et l'adsorption mobile peut être soit localisée soit non localisée.
