Exclusion chromatography can be used to separate molecules on the basis of size 1,2. The technique described here, which uses gel filtration to separate high-molecular-weight DNA from smaller ...

Combining a weakly hydrophobic ion-pairing agent with a moderately hydrophobic one further improved resolution.

It was also around this time that starch helped launch another important nascent separation technology, size exclusion chromatography. Today, column-based separation generally has gone automatic ...

For instance, the stationary phase materials used in the columns can be incredibly expensive, especially for size-exclusion or affinity chromatography. Additionally, chromatography often requires ...
