if sample concentraion is high when we give injection volume low, sample concentraion low give injection volume high, sample concentraion depends upon the sample concentraion, for example caffiene 25 mg 100 ml is high concentraion diluted from 10 ml to 100 ml diluent is meadium concentraion

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 ?
