Question

what is chromatography​

Answer 1

Answer:

process for seperating components of a mixture

Explanation:

eg: to separate drug from blood

Answer 2

Answer:

In chemical analysis, Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a system on which a material called the stationary phase is fixed.

Explanation:

Purpose

The objective of chromatography is to separate the various substances that make up a mixture. The applications range from a simple verification of the purity of a given compound to the quantitative determination of the components of a mixture.

Stationary phase

Stationary phase, in analytical chemistry, the phase over which the mobile phase passes in the technique of chromatography. ... Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary.

Polarity

Polarity has a huge affect on how attracted a chemical is to other substances. ... The larger the charge difference, the more polar a molecule is. You will find that as you increase the polarity of the solvent, all the components of the mixture move faster during your chromatography experiment.

Practical uses

5 Everyday uses for Chromatography

• Creating vaccinations. Chromatography is useful in determining which antibodies fight various diseases and viruses. ...
