Column Chromatography Chemical Synthesis

Chromatography is a technique which is used to for the separation of elements from a compound. There are two phases involved in the process that is stationary and mobile phase. Mixture of whose compounds have to be analyzed is first soaked in the stationary phase and then mobile phase is passed through it. If the composition is correct and proper procedure is followed the compounds from the mixture are easily extracted. The compounds get separated on the bases of absorption and solubility. So, depending on the physical properties chromatography is further classified into two categories - Absorption chromatography and partition chromatography. Absorption chromatography is further classified into Column chromatography and thin layer chromatography and partition chromatography is classified into paper chromatography and gas chromatography.

Column Chromatography

Chromatography is basically a term used for the separation of compounds from a substance. This procedure proves to be very useful when the compounds are available in the substance in very small amount and hence it becomes very difficult to distinguish them from other. This method is also used when those small amount of mixtures present in the compounds have almost same physical or chemical properties. Chromatography is said to be the best and the most convenient method for separation. The method to be adopted in the separation process in chromatography depends on the distribution of components in a mixture during the fixed or stationary and the mobile or moving phase. The stationary phase is said to be the column of absorbent, which can be a paper or a thin layer of any type of absorber on a glass plate or any other thing through which the mobile phase can pass on. The mobile phase can be of liquid or gas. When the stationary phase of a solid takes place in a column it is said to be column chromatography. Column chromatography is said to be one of the best and the most useful method of separation and purification of any solid or liquid substance. It is also said as a solid liquid method of separation where the solid is said to be the stationary phase and liquid is said to be the mobile phase. Column chromatography works on the objective based on the differential absorption of substance based on the capacity of the absorbent. Some of the common absorbents used in column chromatography are calcium carbonate, magnesia, starch, alumina, silica and many more. One the contrary the solvent is selected according to the nature of solvent as well as the absorbent.

Various Chromatography Methods

In organic chemistry, columnchromatography adsorbent is the best purification and separation technique of desired compounds from a mixture. Column chromatography used under two techniques like stationery phase and mobile phase. In which stationery phase is a solid adsorbent, to place in vertical column while as in mobile phase is a liquid, is add from the top and solvent flows down through the column by gravity or by the air pressure. The stability is required to maintain between the liquid flowing down though the column and adsorbents. Because in the mixture, there are different components having different interactions with the mobile phase and stationery phase.

There are four types of methods used in silica gel column chromatography. That is analytical chromatography which is used to analyze that how much percentage of mixture is to be purified. This is a very fast and cost effective method for separation. Another is preparative chromatography, which is used to optimize the opportunities of the process and also improves the process of separation. Next is process chromatography where the separation is taken up to a biologics level and separation of proteins, viruses, hormones and anti-bodies is now possible. The last is gravity chromatography which is said to be the manual process. The mixture is allowed to move around by gravitational force.
