Stationary phase in ion chromatography
WebNov 24, 2024 · The stationary solid phase generally consists of covalently attached anions or cations with an insoluble matrix called ion exchangers. Ion exchangers It is made up of two parts- an insoluble matrix and chemically bonded charged groups within an on the surface of the matrix. WebAug 15, 2024 · In normal phase chromatography, the stationary phase is polar, and so the more polar solutes being separated will adhere more to the stationary adsorbent phase. When the solvent or gradient of solvents is passed through the column, the less polar components will be eluted faster than the more polar ones.
