WebChromatography column In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions. WebThere are many types of chromatography e.g., liquid chromatography, gas chromatography, ion-exchange chromatography, affinity chromatography, but all of these employ the same basic principles. Chromatography is a separation … WebAn ion (/ ˈ aɪ. ɒ n,-ən /) is an atom or molecule with a net electrical charge.The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.The net charge of an ion is not zero because its total number of electrons is unequal to its total number of … floating fortress 1984
