  2. Gel permeation chromatography - Wikipedia

    en.wikipedia.org/wiki/Gel_permeation_chromatography

    Gel permeation chromatography (GPC) has become the most widely used technique for analyzing polymer samples in order to determine their molecular weights and weight distributions. Examples of GPC chromatograms of polystyrene samples with their molecular weights and dispersities are shown on the left.

    An autosampler for liquid or gaseous samples based on a microsyringe Different kinds of autosamplers exist. Autosamplers can be classified in relation to sample capacity (auto-injectors vs. autosamplers, where auto-injectors can work a small number of samples), to robotic technologies (XYZ robot [ 11 ] vs. rotating robot – the most common ...

  9. CpG site - Wikipedia

    en.wikipedia.org/wiki/CpG_site

    CpG is shorthand for 5'—C—phosphate—G—3' , that is, cytosine and guanine separated by only one phosphate group; phosphate links any two nucleosides together in DNA. . The CpG notation is used to distinguish this single-stranded linear sequence from the CG base-pairing of cytosine and guanine for double-stranded sequenc
