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 ...

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 ...

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

Characterization of the molecular weight distribution of organic matter Size exclusion chromatography (SEC) is a technique used to assess the molecular weight distribution of organic matter. The ...

Typically, aggregates are identified using size exclusion chromatography. However, recovering the samples after this analysis is difficult and often time-consuming. Never miss a story ...

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 ...
