WebSize-exclusion chromatography (SEC), also known as molecular sieve chromatography, is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers.Typically, when an aqueous solution … Webachieved with operation at ~40 °C. Gradient-elution techniques for this packing often use 5% methanol or acetonitrile as the initial sol-vent and 100% methanol or acetonitrile as the final solvent.

Therefore, eluate is what we are interested. • We add eluent to the column, and eluate is what is coming out of the column. • We can determine and control what we add as the eluent, but the nature of eluate is dependent on the eluent. We cannot control its constituents 100%.
