What are the applications of Chromatography?

In molecular biology, the studies of proteomics and metabolomics frequently rely on combining different chromatographic techniques, with one notable example being EC-LC-MS. Additionally, chromatographic methods are extensively utilized in nucleic acid research. Specifically, a type of chromatography called HPLC is commonly utilized for separating proteins. Chromatography is also widely used in the pharmaceutical industry to detect and identify tiny amounts of chemicals and elements present in a sample. It also plays a role in drug development, allowing for the detection of impurities and unknown compounds in drug samples. Additionally, it facilitates the analysis of drug sample purity. Chromatography is also used for separating specific chemical compounds according to their molecular weights or, in some cases, the elements they contain. Chromatography is essential in the chemical industry for ensuring the purity of water samples and analyzing air samples for contaminants. This technique is also crucial in the food industry for assessing the shelf life of food products by analyzing the point at which they spoil; it also aids in identifying chemical additives present in food products.
