Rp hplc column. Reversedphase HPLC (RPHPLC) is the most commonly used mode of HPLC and, as the name implies, this mode is just the reverse of NPHPLC, whereby the stationary phase is more nonpolar than the eluting solvent Generally, RPHPLC has a nonpolar stationary phase, eg, C 18 silica (Table 191), and a moderately polar aqueous mobile phase 8,10. A reverse phase column, or reversedphase HPLC columns, are chromatography columns that contain a nonpolar stationary phase Reverse phase columns are widely used in many disciplines, such as pharmaceuticals, the petroleum industry, forensics, and clinical sciences, to separate chemical compounds into their individual parts for purification or analysis. The key difference between reverse phase and normal phase HPLC is that the reverse phase HPLC uses a nonpolar stationary phase and a polar mobile phase whereas the normal phase HPLC uses a polar stationary phase and a less polar mobile phase The normal phase HPLC is the oldest technique of HPLC that Tswett used in his separations of plant extracts;.
