Question

Which of the following statement is NOT true about liquid chromatography? Among the four modes of LC separations we discussed in the class, size exclusion chromatography is the only mode of separation that does not involve the chemical interactions between the analyses and the stationary phase materials. Gel permeation chromatography is often employed for the separation of proteins. In size exclusion chromatography, molecules with sizes that are smaller than the pore size of the packing material tend to have longer retention time. For size exclusion chromatography, small variation in pore size is often important to achieve satisfactory

Explanation / Answer

The 2nd statement " Gel permeation chromatography is often employed for the separation of proteins" is NOT true. It is often used for the separation of polymer.
