Separation Techniques | Paper Chromatography

At the end of this video, you will be able to describe how to carry out a paper chromatography experiment and understand the rationale for the various precautions we take while doing paper chromatography.
We will be separating inks obtained from different coloured markers.

Thank you all for your comments and support, glad you found this useful!

[@MrJansenTan]

The Rf value is the distance travelled by the solute divided by the distance travelled by the solvent. The distance travelled by the solute is the length measured from the start line to the centre of the spot. The distance travelled by the solvent is the length measured from the start line to the solvent front.

[@troliie]

Why is it best to use the farthest distance traveled by a sugar if and when the solvent went over the paper?

[@redhorse4716]

Very helpful. This might be one of the few videos about chromatography that not only demonstrated how to do the procedure, it also taught what the purpose of the procedure. A lot of the videos here in youtube doesn't tell what the point of chromatography is.

wow, this is really good. it's literally almost exactly how TLC works, and just with paper chromatography! very well made.

Chromatography is a technique used to separate small amounts of substances from a mixture based on the different solubility of the components in the particular solvent. - What is the main advantage of using chromatography? -Only a small sample is required -It can be used as a method to determine if the sample is pure. - Why is water a suitable solvent? -Because the samples are soluble in water. - Why do we have to cover the beaker with a lid? -To minimize the evaporation of solvent. -To ensure that the atmosphere in the beaker is saturated with solvent vapor. -Saturating the atmosphere in the beaker with vapor stops the solvent from evaporating as it rises up the paper. - If the dye is not well separated, we can consider changing the solvent.

[@tessa3076]

We did it in class without a lid and it worked fine why is that?

[@MrJansenTan]

For solvents that are not too volatile, it still works without a lid. The correct practice of course is to include the lid, which is how it is done in practice by organic and analytical chemists using the method called Thin Layer Chromatography. You can read more about it here: www.chemguide.co.uk/analysis/chromatography/thinlayer.html

[@BreakfastTime765]

Sorry but may I know why the most soluble substance is on the top of the paper? I don’t really understand the concept 😭 thank you 🙏

[@MrJansenTan]

Both the paper (we call it the stationary phase) and the solvent (we call it the mobile phase) have an attraction for the substance. If the sample is more attracted (a.k.a. more adsorbed) to the paper, it is less likely to be carried by the solvent and therefore travels a shorter distance. If the sample is more soluble in the solvent (i.e. less adsorbed by the paper), it is more likely to be carried up further by the solvent. How much a sample is adsorbed onto the paper or dissolved in a solvent is determined by the concept of polarity. This is why different solvents or different materials used to make the stationary phase would affect the Rf values.

We measure the distance from the pencil (start) line to the centre of the spot.

Can we use other paper than filter paper

Yes you can try with coffee filters
