Answer / nagendra rane
Specific Optical Rotation [α]tλ = 100 x a
---------
l x C
Where Specific Optical Rotation at temperature “t” and “λ”
is wavelength
a = Optical Rotation
l = length of Polarimeter tube
c = Concentration
The average Specific Optical Rotation of Dextrose
α = +52.76
Therefore C = 100 x a (Optical rotation)
---------------------------
2 x α
C = 100 x a (Optical rotation)
---------------------------
2 x 52.76
C = a X 0.9477
Concentration of Dextrose(C)= OR(a) x 0.9477

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 ?
