Question
Which of the following method is used for checking the purity of pharmaceuticals?
- Crystallization
- Decantation
- Boiling
- Chromatography
Hint:
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.
