How to fill out paper chromatography - interchemnetummaineedu

How to fill out paper chromatography - interchemnetummaineedu:

1. Gather the necessary materials, including chromatography paper, a solvent, sample solutions, and a container for the experiment.
2. Cut a strip of chromatography paper to the desired length, making sure it is long enough to reach the bottom of the container.
3. Prepare the sample solutions by diluting them if necessary and ensuring they are in liquid form.
4. Use a pencil to draw a horizontal line near the bottom of the chromatography paper, leaving some space below the line.
5. Apply a small amount of each sample solution onto the line using a capillary tube or a spotter, making sure to space them out evenly.
6. Pour the solvent into the container, making sure it is deep enough to immerse the bottom of the chromatography paper.
7. Place the chromatography paper in the container, ensuring that the sample solutions are above the level of the solvent but not submerged.
8. Wait for the solvent to travel up the paper, carrying the separated components of the sample solutions with it. This process may take several minutes.
9. Remove the chromatography paper from the container once the solvent has reached the desired height or until separation is clearly visible.
10. Allow the paper to dry completely before analyzing the results or storing it for future reference.

Who needs paper chromatography - interchemnetummaineedu:
