WebAug 15, 2024 · Normal phase HPLC is only rarely used now, almost all HPLC separation can be performed in reverse phase. Reverse phase HPLC (RPLC) is ineffective in for … WebDec 30, 2024 · A rule of thumb I use is if the sample is organic solvent soluble (DCM, EtOAc, toluene, ether, etc.) then try normal-phase. If the crude material is soluble in polar solvents (alcohols, DMSO, DMF, acetonitrile, etc.) then I first suggest reversed-phase. If the sample is hydrocarbon soluble (hexane, heptane, cyclohexane) then I think reversed ...
