Q1. RP-HPLC Stands For?

(A) Reverse Pressure HPLC
(B) Red Phase HPLC
(C) Reverse Protein HPLC
(D) None

ANSWER – (A) Reverse Pressure HPLC

• This Mode Is Just The Reverse Of NP-HPLC, Whereby The Stationary Phase Is More Nonpolar Than The Eluting Solvent.Therefore, Polar Molecules In The Mixture Spend Most Of Their Time Moving With The Solvent.
