Chromatography can be used to separate delicate products. Chromatography is a very special separation process for so many reasons. Chromatography involves a sample being dispersed in a mobile phase (Such as liquid, gas or a supercritical fluid). The mobile phase is then allowed to go through an immobile, immiscible stationary phase. The phases are chosen in such a way that components of the sample must differ in their solubility in each phase. A component which takes more time to travel which is most utterly soluble in the stationary phase than a less soluble component in the stationary phase. As a result of these differences in mobilities, sample components will be separated from mixture as they travel through the stationary phase.
Gas chromatography is one of the analytical techniques used for separation and analyzing compounds. Prototypical uses of GC are to check the purity of a particular substance(Molecule or compound) or separation of the different components of a mixture. The sample solution enters a gas stream when injected into the instrument. It transports the sample into a separation tube known as the "column." (carrier gases used here are Helium or nitrogen) The inside the column various components get separated. A standard sample with known concentration is injected into the instrument for the measurement of a sample with an unknown concentration,. The standard sample peak retention time (appearance time) and area are compared to the test sample to calculate the concentration.
Liquid chromatography–mass spectrometry (LC-MS)
Liquid chromatography–mass spectrometry (LC-MS) is one of the analytical techniques. It is most often cited technique for the liquid chromatographers. This technique combines the resolving power of liquid chromatography with the detection specificity of mass spectrometry. Liquid chromatography (LC) introduces sample components into the mass spectrometer (MS) by separating them. The MS ionises the molecule and detects charged ions. Mass spectrometry provides structural identity of the individual components with high molecular specificity and detection sensitivity & liquid chromatography separates mixtures with multiple components. This spectroscopic technique is being used to analyze inorganic, organic, and biochemical compounds, commonly found in complex samples of biological and environmental origin.
High performance liquid chromatography (HPLC)
High performance liquid chromatography (HPLC) is basically a highly improved form of column liquid chromatography. It is an analytical technique used to separate, identify, and quantify each component in a mixture. Instead of a solvent being allowed to run through a column under gravity, it is forced through under high pressures (400 atm). That makes it much faster. Including HPLC all chromatographic separations works under the same basic principle; Because of the difference in the relative affinities of different molecules for the mobile phase and stationary phase used in this separation will separate the sample into its respective components.
Ion chromatography (or ion-exchange chromatography) basically separates the molecule into its ions and polar molecules based on their affinity to the ion exchanger. Most preferably it works any kind of charged molecule, including large proteins, small nucleotides, and amino acids. The two types of ion chromatography are anion-exchange and cation-exchange. It is often used in quality control, protein purification and water analysis.
Affinity chromatography (AC) is an analytical technique used for the purification of a biomolecule with respect to individual chemical or structure biological function. Affinity chromatography is widely used for protein purification. AC is designed to purify a particular molecule from a mixed sample. In summary, It is a method that is designed to purify a particular molecule from a mixed sample so that we can carry out further investigation of this molecule.
Supercritical Fluid Chromatography
Supercritical Fluid Chromatography (SFC) is a form of normal phase chromatography, first used in 1962, which is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules. It can also be used for the separation of chiral compounds. Principles are similar to those of high performance liquid chromatography (HPLC), however SFC typically utilizes carbon dioxide as the mobile phase; therefore the entire chromatographic flow path must be pressurized. Because this supercritical phase of being pressurized situation represents a state in which liquid and gas properties meets, it is sometimes called as “convergence chromatography”.
