Chromatography Forum

Chromatography first term in 1903 by the Soviet chemist Mikhall Tswett with gypsum, in the chlorophyll and the introduction of separation. Mean colorless in the pole appeared on the color of the band. Modern means that covers all based on samples in the mobile phase (gas or supercritical) and at a fixed phase (liquid or solid) derived from distribution technology. Chromatography is a separation process, one built on the absorption, distribution, ion-exchange, affinity and molecular size, and so on the basis of the separation process. He used the relative movement of different components, different from each other of the two phases, with a relatively static for the stationary phase, while another relative movement of the mobile phase, the use of absorption capacity, distribution coefficient, ion-exchange capacity, or affinity Elements such as the nature of the small size difference, after two-and several times in a row, the quality of exchange, so that the different components are separated.
Chromatography analysis as a means of detection, can be used to determine the constant low molecular weight or trace gases, but also from millions of molecular detection of natural or synthetic substances; detachable nature is very close to the isotope, with the isomers, space vary Constitutive of, or optical isomers spin heterogeneous Enantiomers, also widely used in biological macromolecules, or some active substances, such as peptides, nucleic acids, proteins and ions of yin and yang, it has become organic and some inorganic Determination of the important means for the oil, chemical, environmental protection, medicine, biological and chemical research and production departments in the detection of separation an indispensable tool. Chromatography of the first importance is that it is very close to the nature of the material of the separation possible. This is the modern chemical, biological and other research and development in an extremely important and indispensable means of separation.
that's right?

Dear chenhongxia,
Is your writing for a high-school poster? It seems that you have touched on many areas superficially, but there was a "Lost in Translation." I certainly believe that you could improve your writing a lot more. For example,

Chromatography first term in -- > The word "chromatography" was coined in 1903..

Mean colorless in the pole appeared on the color of the band. --> Colorless objects can be separated into colored bands.

determine the constant low molecular weight --> determine the MW distribution(?)

detachable nature is very close to the isotope -->> [Sorry, I could not understand you here]

Chromatography of the first importance --> The technology is important ...

As Alfred88 indicated, the writing needs to be improved by a native English speaker or technical writer. It looks to me as an attempt to translate the writing from a foreign chromatography book in English.

Some history reading would be advisable too. In 1903, for example, there was no such a union called Soviet.
The first name of the man in question was not Mikhall but Mikhail and he was not a chemist but botanist.
