Web18 feb. 2013 · In ion exchange SPE, extraction is mediated by electrostatic interactions between charged chemical groups on both the solid phase and the analyte of interest. It is typically used to separate large proteins, amino acids, or nucleotides based on their charge. Proteins, for example, can have a variety of positively or negatively charged groups ... WebThe difference is in the functional groups on the SPE phase and their charge state. The strong ion exchange phases are called “strong” because the sulfonate cation or quaternary ammonium anion exchange group remain charged over the entire pH range. They are always positively or negatively charged, regardless of pH conditions.
