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 ...

Flash column chromatography is a method of chemical separation that is used to purify chemical mixtures. It is also known as flash purification, due to its function ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

Micellar electrokinetic chromatography is a modified version of capillary electrophoresis which is used to separate a wide range of molecules, from inorganic ions to large biopolymers. Electrophoresis ...

Gas chromatography is a common chromatography technique used to separate and analyze volatile chemical compounds which do not decompose. It is typically used to separate different compounds within a ...

Liquid chromatography (LC) is a chromatographic technique used to separate and analyze mixtures of chemical components in solution, to determine if a specific component is present or absent and, if ...

This video reviews the advantages of using mixed-mode chromatography media. Mixed-mode chromatography depends on more than one interaction principle occurring between stationary phase and solute.

The biopharma industry is looking at continuous chromatography for sensitive molecules. Continuous processes continue to advance in bioprocessing. In downstream processing, continuous chromatography ...

Vermont is known for beautiful fall colors. Every Autumn, the green leaves change into a wonderful collage of oranges, yellows, and reds. It may seem like the colors just appear out of nowhere, but ...
