Answer / santosh

In normal phase , stationary phase is polar while mobile
phase is non polar & separation is achieve by the polarity
of the compound. More polar compound eluted out last while
non polar compound eluted fast

Answer / nagaraj

in normal phase chromatography is used for seperation of
compounds which are having non polar segments .if we take
non polar asorption can acheived against separtion.because
it is seperation chromatogrphy.

Answer / amol

In normal phase , stationary phase is polar while mobile
phase is non polar & separation is achieve by the polarity
of the compound. More polar compound eluted out first while
non polar compound eluted last . if we take non polar
stationary phase it will happen reverse..
