  7. 1 The polarity index is a measure of the relative polarity of a solvent and is useful for identifying suitable mobile phase solvents. The polarity index increases with polarity. For reverse phase chromatography eluent strength decreases as its polarity increases 2 UV cutoff, the wavelength at which the solvent absorbance in
