Question

Which of the following method is used for checking the purity of pharmaceuticals?

  1. Crystallization
  2. Decantation
  3. Boiling
  4. Chromatography 

hintHint:

Chromatography is a laboratory technique for the separation of a mixture into its components.

The correct answer is: Chromatography


    Chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.
    Chromatography is used for checking the purity of pharmaceuticals.
