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!

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?

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

[@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.

What is chromatography?
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.

How do we take the distance travelled by a colour? Where exactly we mark the dot?

[@MrJansenTan]

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

[@kshitijgupta5234]

Thank you sir

[@davidlee50]

What is the solvent for food grade experiments? Like from plants and seeds?

[@MrJansenTan]

It depends on your choice of stationary phase as well as the pigments you intend to separate. For example, if you're separating the pigments in spinach leaves (chlorophyll, xanthophyll, carotene) on silica TLC plates, you can try n-hexane:acetone (7:3 v/v). You can find the procedure quite easily on other websites or in science journal articles.

Sir please tell me how we select different paper chromatography techniques on the base of type of substance being separated?.....reply plzzz

[@MrJansenTan]

Hi Hifza, in general, you would have to consider the polarity of the substances you intend to separate. Then choose an appropriate solvent or solvent mixture from there.
