The Work Process and how to use what is the stationary phase in paper chromatography
In paper chromatography, the stationary phase is the piece of filter paper that serves as the medium for separating the components in a mixture. The stationary phase is typically a thin strip of paper that has been saturated with a solvent or a mixture of solvents.
To use the stationary phase in paper chromatography, first, prepare the filter paper strip by cutting it to the desired size and saturating it with the solvent. The solvent should be chosen based on the components being separated in the mixture.
Next, apply the mixture to be separated to the bottom of the filter paper strip using a small spot or line. Allow the spot to dry completely before proceeding.
Once the spot is dry, place the filter paper strip in a container with a small amount of the chosen solvent in the bottom. The solvent should not cover the spot on the filter paper.
As the solvent travels up the filter paper strip through capillary action, it will carry the components of the mixture with it. Each component will interact differently with the stationary phase based on its affinity for the solvent and the paper.
After the solvent has traveled a sufficient distance up the filter paper strip, remove the strip and mark the solvent front. The distance traveled by each component can be measured from the original spot to its final position.
The stationary phase in paper chromatography is crucial for separating the components of a mixture based on their affinity for the solvent and the paper. By understanding how to use the stationary phase effectively, you can analyze and identify the components in a mixture with precision.
