Paper chromatography

Paper chromatography, separating coloured inks (vertical streaks). Chromatography is an analytical process that separates a compound into its constituent chemicals. Chromatography paper with the ink on it is dipped vertically in a solvent. Capillary action draws the solvent up through the paper, dissolving the ink. As the solvent travels up the paper it takes the various chemicals in the ink with it, separating them into a series of coloured bands

EDITORS COMMENTS
This print from Science Photo Library showcases the fascinating process of paper chromatography. In this image, we witness the separation of various colored inks through vertical streaks on a piece of chromatography paper. The technique of chromatography is an essential analytical tool that allows us to break down compounds into their constituent chemicals. The experiment begins by dipping the chromatography paper with ink vertically into a solvent. Through capillary action, the solvent ascends through the paper, dissolving and carrying along the different chemicals present in the ink. As it travels upwards, an intriguing transformation occurs - distinct bands of vibrant colors emerge, each representing a separate chemical component. This mesmerizing display serves as a valuable lesson in chemistry for students at school. By observing this phenomenon unfold before their eyes, they gain insight into concepts such as solubility and color analysis. It sparks curiosity and encourages further exploration into understanding how substances interact and behave. The intricate details captured within this photograph highlight not only the beauty but also the scientific significance behind paper chromatography. It reminds us that even seemingly ordinary objects like pens can hold hidden complexities waiting to be unraveled through careful observation and experimentation.
