the column for separation. Analytes can be desorbed in a moving stream of mobile phase (dynamic desorption), or the fiber can be soaked in mobile phase for a specific period of time before the analyte is injected onto the column (static desorption). The interface consists of a desorption chamber, a six port injection valve, and a mounting bracket.

Adsorption, Absorption and Desorption What's the

Adsorption and desorption are the main processes operating in chromatography. It is the relative rates of adsorption and desorption onto and off the stationary phase that allows chemicals in samples to be separated. If the column conditions favour adsorption of a molecule, then the molecule will adhere to the stationary phase and be separated from the other sample chemicals.
