Chromatography

Jan 08, 2020Chromatography- Principle, Types and Applications. Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis. The Russian botanist Mikhail Tswett coined the term chromatography in 1906.

What Is Chromatography?

Apr 03, 2014A chromatography tutorial from the University of Wisconsin-Madison explains: The eluting solvent should [] show a maximum of selectivity in its ability to dissolve or desorb the substances being separated. The fact that one substance is relatively soluble in a solvent can result in its being eluted faster than another substance.

Chromatography

Although there are numerous types of chromatographic methods, there are several factors that are common to all types. All chromatographic systems have a mobile and a stationary phase. Regardless of the type of chromatography, samples are dissolved in the mobile phase, which travels through the stationary phase. Separation is possible because different compounds have different affinities for the

Chromatography

Chromatography is a method of separating the constituents of a solution, based on one or more of its chemical properties. This could be charge, polarity, or a combination of these traits and pH balance.
