The difference in concentration of ion-pairing agent between the two eluents is generally not large enough to adversely affect the separation. A typical example would be to use 0.065% TFA in eluent A and 0.05% TFA in eluent B.
WebIon pair reversed-phase (IP-RP) chromatography is one of the most common techniques used for ON analysis and small-scale purification.1-4 ONs are polar products and carry … WebIon pair chromatography (IPC) is an effective reversed-phase liquid chromatographic (RPLC) technique for separation of organic ions and partly ionized organic analytes. The …
WebIon pair chromatography typically uses a reversed-phase column in conjunction with a special type of chemical in the mobile phase called an ion-pairing reagent. “Reversed phase” essentially means that the column’s stationary phase is nonpolar (less polar, more organic) than the mobile-phase solvents.
