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 ...

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 ...

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 ...
