normal-phase chromatography, such as ink on paper; reverse-phase chromatography, often used in university lab experiments; gas chromatography, seen in airport bomb detectors “capture ...

In this experiment, the water moves across the paper by a force called capillary action. The water carries some parts of the ink components further than others, and the colors separate out into a ...

As a result, components of the solution separate and, in this case, become visible as strips of color on the chromatography paper. Will your marker ink show different colors as you put it to the test?

The idea behind this experiment’s use of paper chromatography is that as the ink is carried up the paper by the water, the different dyes in the ink will separate depending on how much they ...

As the water travels through and down the paper, it picks up ink particles and carries them along with it. This same process can be put to good use as a technique called paper chromatography. On ...

Chromatography is used to separate the given components of a mixture that have differing solubilities in a solvent. It can be used to separate coloured substances in a mixture, like the inks in ...
