Chromatography is the collective term for a set of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a “mobile phase” through a “stationary phase”, which separates the analyte to be measured from other molecules in the mixture based on differential partitioning between the mobile and stationary phases. Chromatographic techniques can be classified according to several different criteria:
- Shape of the stationary bed :- column or planar
- Displacement or elution
- Physical state of the mobile phase :- gas, liquid or supercritical fluid
- Separation mechanism :- ion exchange or size-exclusion
