WebChromatography - Key takeaways. Chromatography is a separation and analytical technique used to split a soluble mixture into its component parts. Chromatography involves a static medium, known as the stationary phase, a solvent, known as the mobile phase, and a mixture that you want to analyse. Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition.
