Your software could be run in various ways – isocratic and gradient. Isocratic is when the mobile phase mixture is steady more than the entire testing time.

SEC is utilised largely for the analysis of large molecules for example proteins or polymers. SEC performs by trapping these more compact molecules within the pores of a particle. The much larger molecules merely pass through the pores as They may be too substantial to enter the pores. More substantial molecules consequently move in the column more rapidly than scaled-down molecules, that is, the more compact the molecule, the more time the retention time.

Distinct compounds have distinctive retention periods. more info For a particular compound, the retention time will change determined by:

By far the most popularly applied CSPs in pharmaceutical chemistry are polysaccharide benzoate and phenylcarbamate derivatives.
