Flash column chromatography was developed in 1978 as an alternative method to long column chromatography. The method aims to isolate a component from a mixture and thereby purify it. It was built from ...

As this silica column separated Çağrı Özsan’s reaction mixture, he and his labmate Veselin Nasufović noticed a curious pattern arise. Sitting atop their column, they recognized the flag of Germany, ...

ASK A DOZEN CHEMISTS about the forces that drive innovation in high-performance liquid chromatography, and nearly all of them will agree: When it comes to chemical separations, the name of the game is ...

Sometimes a scientist needs to figure out what is in a certain mixture of substances. One way they can do this is to use a process called chromatography. In the activity below, you can try ...

The term liquid chromatography (LC) refers to a class of physicochemical methods which are used to separate and quantify compounds in a sample. LC is made up of a liquid mobile phase, which carries ...

One-dimensional gas chromatographic (1D-GC) analyses of complex environmental, petrochemical, or biological samples often result in a chromatogram with a large portion of unresolved components. Mass ...
