Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments. This can also be used in secondary or primary colors in ink experiments. This method has been largely replaced by thin layer chromatography, however it is still a powerful teaching tool. Two-way paper chromatography, also called two-dimensional chromatography, involves using two solvents and rotating the paper 90° in between. This is useful for separating complex mixtures of similar compounds, for example, amino acids.

Which chromatographic process would be least likely to be utilized in the crime lab?
paper chromatography
How to do Chromatographic technique to study root stem transition?
we can do this technique by a proper method.first we have to take the cut part of a root stem n then grind it by machine n then spread this solution on chromatographic paper ......when the paper becomes dry we can see the transition of different colours...
WHAT ARE THE 5 SEPARATION TECHNIQUES FOR CHEMISTRY?
Five examples of separation are: filtration, distillation, decantation, ion exchange, centrifugation.
Paper used in chemistry experiments?
Filter paper is used regularly in chemistry experiments, for suction filtration and waighing out compounds.
What problems may arise in the use from a poorly packed liquid chromatography column?
The effect of packing a chromatographic column unevenly will cause the flow to be uneven down the column and lead to poor separation.

Why is it good to use alcohol when doing chromotography?
Alcohol is used only in the chromatographic separation of substances that do not dissolve in other common solvents but dissolve in alcohol.
What are the considerations in choosing a chromatographic solvent?
One of the considerations of a chromatographic solvent is whether it will bring out the different Rf values of the samples that are being used. If all of the compounds have the same Rf values then the separation of pigments would have failed due to the fact that all of them are in the same spot.
