... The reference atom (isotope) was a particular isotope of carbon (C), i.e., “carbon-12”. It was symbolized as: 12C. The mass of one atom of this particular carbon atom was defined as exactly 12.0000…. atomic mass units (amu). So, the conversion factor is: 1 atom of 12C = 12.00… amu. This means that t ...

Size-exclusion chromatography



Size-exclusion chromatography (SEC) 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 is used to transport the sample through the column, the technique is known as gel-filtration chromatography, versus the name gel permeation chromatography, which is used when an organic solvent is used as a mobile phase. SEC is a widely used polymer characterization method because of its ability to provide good molar mass distribution (Mw) results for polymers.
