تعريف chromatography في الإنجليزية الإنجليزية القاموس.

Any of various techniques for the qualitative or quantitative separation of the components of mixtures of compounds; all characterised by the use of a mobile phase (gas or liquid) moving relative to a stationary phase (liquid or solid) - the differences between the rates of migration of the compounds between the two phases effects the separation

a technique used to separate components in a sample mixture by the differential distribution of the components between a mobile phase and a stationary phase

A way of separating different coloured substances in a liquid

A technique for separating the components of a mixture on the basis of differences in their affinity for a stationary and mobile phase

An analytical technique whereby a complex substance is adsorbed on a solid or liquid substrate and progressively eluted by a flow of a substance (the eluant) in which the components of the substance under investigation are differentially soluble The eluant can be a liquid or a gas When the substrate is filter paper and the eluant a liquid, a chromatogram of colored bands can be developed by use of indicators For gas chromatography, electronic detectors are normally used to indicate passage of the various components from the system

a process used for separating mixtures by virtue of differences in absorbency

Laboratory separation technique based on selective adsorption by which complex mixtures can be identified Silica gels with specific size and pore structure can be used in this process

The separation of chemical substances by making use of differences in the rates at which the substances travel through or along a stationary medium

{i} method of separating mixtures and identifying their components (Chemistry)

The separation of two or more chemical compounds in solution by their removal from the solution at different rates (CMD 1997)

Literally the process of separation by color, but is used most often to described the process of separation of a complex mixture into individual components using the principles of differential sorption (i e , adsorption and desorption from a chromatographic column)

the separation of a liquid or gaseous mixture by passage over an adsorbent so that each component becomes adsorbed separately

A method of separating a solution of closely related compounds by allowing it to flow through an adsorbent so that each compound becomes separated It is the most advanced technology to separate proteins, such as in plasma fractionation

The separation of a mixture of substances by charge, size, or other property by allowing the mixture to partition between a moving phase and a stationary phase

Method first described in 1903 by Mikhail S. Tsvet for separating mixed chemical substances. Tsvet's neglected work, rediscovered in the 1930s, uses the different affinities of substances in a solution in a mobile phase (a moving stream of gas or liquid) for adsorption onto a stationary phase (a fine-grained solid, a sheet of filtering material, or a thin film of a liquid on a solid surface). Choices of materials for these phases allow enormous versatility for separating substances including biological fluids (e.g., amino acids, steroids, carbohydrates, pigments), chemical mixtures, and forensic samples. In the original technique, an organic solvent flowed through a column of powdered alumina (see aluminum), sodium carbonate, or even powdered sugar to separate mixed plant pigments. Among current adaptations are paper chromatography (PC), thin-layer chromatography (TLC), liquid chromatography (LC, including high-performance liquid chromatography, or HPLC), and gas chromatography (GC). Some remain laboratory techniques, but others (especially HPLC) can be used on an industrial scale. They require different methods for detecting and identifying the separated components, including colorimetry, spectrophotometry, mass spectrometry, and measurement of fluorescence, ionization potential, or thermal conductivity. A.J.P. Martin shared a 1952 Nobel Prize for developing LC and PC, and in his Nobel lecture announced the development (with his cowinner R.L.M. Synge and other colleagues) of GC. gas chromatography paper chromatography thin layer chromatography

A physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary (stationary phase) while the other (the mobile phase) moves in a definite direction [IUPAC Compendium]

this process involves a sample being vapourised and injected onto the head of the chromatographic column The sample is transported through the column by the flow of inert, gaseous mobile phase The column itself contains a liquid stationary phase which is adsorbed onto the surface of an inert solid

A technique for separating the components of a mixture on the basis of differences in their affinity for a stationary and a mobile phase

Chromatography is a method for separating mixtures based on differences in the speed at which they migrate over or through a stationary phase

The separation of chemical substances and particles by differential movement through a two-phased system [22]

A generic term for any one of several powerful procedures used to separate one type of molecule from another Chromatography always involves use of two phases: 1) a "mobile" phase, which is usually the liquid, and 2) a "stationary phase", which is usually the solid support that the liquid mobile phase runs thru The stationary solid phase is usually held in a glass pipe, or column, and the liquid mobile phase passes thru the stationary phase, often simply due to gravity pulling it thru Ideally, the different molecules one is separating out have different affinities, or propensities, to be in one phase or the other more often For example, if the molecules you don't want to keep spend more time in the solid stationary phase, they won't come out of the bottom of the column as quickly as the molecules you do want, which having spent more time in the liquid mobile phase therefore come out of the column the fastest see also nickel chromatography

A process to separate the components of a mixture, based on size, charge or other chemical properties

a way of finding out which substances a mixture contains by passing it through or over something that absorbs the different substances at different rates

A treatise on colors a process used for separating mixtures by virtue of differences in absorbency

A procedure used to identify substances, such as drugs of abuse, in urine The substance is separated or extracted, allowed to move or migrate along a carrier, and then identified

A method of separating a mixture of compounds by the use of a porous material

gas chromatography

Type of chromatography with a gas mixture as the mobile phase. In a packed column, the packing or solid support (held in a tube) serves as the stationary phase (vapour-phase chromatography, or VPC) or is coated with a liquid stationary phase (gas-liquid chromatography, or GLC). In capillary columns, the stationary phase coats the walls of small-diameter tubes. The sample of gas or volatile liquid to be analyzed is injected into the inlet; its components move through with a carrier gas (usually hydrogen, helium, or argon) at rates influenced by their degree of interaction with the stationary phase. The temperature, nature of the stationary phase, and column length can be varied to improve separation. The gas stream issuing from the column's end may pass through a thermal conductivity detector or a flame ionization detector, where its properties are compared with those of known reference substances. GC is used to measure air pollutants, essential oils, gases or alcohol in blood, and composition of industrial process streams

gas chromatography

chromatography by means of gas for the purpose of analysis

paper chromatography

Type of chromatography using filter paper or other special paper as the stationary phase. Spots of sample and reference materials are applied, usually as liquids, near one edge (or corner, for two-dimensional PC) of the paper. The edge of the paper is dipped in a solvent, which travels along it by capillarity, moving the components of the sample at rates depending on their relative solubilities in the solvent. In two-dimensional PC, the paper is then turned 90° and the new edge dipped in a different solvent. The components of the sample mixture, visible as separated spots, are identified by comparing the distances they have traveled with those of the known reference materials. PC is especially useful for complex mixtures of amino acids, peptides, carbohydrates, steroids, and many other organic compounds and inorganic ions

thin-layer chromatography

Type of chromatography using as the stationary phase a thin layer (0.01 inch [0.25 mm]) of a special finely ground matrix (silica gel, alumina, or similar material) coated on a glass plate or incorporated in a plastic film. Solutions of the mixtures to be analyzed are spotted near one edge. Solutions of reference compounds are similarly applied. The edge of the plate is then dipped in a solvent. The solvent travels up the matrix by capillarity, moving the components of the samples at various rates because of their different degrees of attachment to the matrix and solubility in the developing solvent. The components, visible as separated spots, are identified by comparing the distances they have traveled with those of the known reference materials. TLC is useful for biological mixtures, especially lipids in animal or vegetable tissues and isoprenoids and essential oils found in flowers and other parts of plants. The matrices withstand strong solvents and developers better than the paper used in paper chromatography
