In HPLC Chromatographic separation Resolution equation is Rs = 1.18 (tR2 –tR1)/wh1+Wh2, Where, tR2 and tR1 is run time of eluent ratios of the distances from the point of application to the centers of the spots and the distance travelled by the solvent front from the point of application (retardation factor), and Wh1and Wh2 , is peak width of at half height. What is 1.18 ?
