explain chromatography with suitable diagram
Answers
Answer:
Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.
Answer:
chromatography: it's derived from Greek root word "chroma" meaning colour. It originate from it's initial use of separation of plant leave pigments as colour bans on the column of calcium carbonate.
Chromatography can also be defined as a separation process which is used for separation of essential molecular mixtures. it's separation ability depends on differential retardation or retention carried out by unequal absorption of different components, carried along by a stream of innert liquid or gas.
