Chromatology, also known as chromatography, is a scientific technique that separates and identifies sample components by utilizing their different interactions with a medium. There are several synonyms for the word chromatology, including chromatography analysis, column chromatography, gas-liquid chromatography, liquid-liquid chromatography, and paper chromatography. Chromatography analysis is commonly used in the field of chemistry to separate complex mixtures, while column chromatography involves the use of a column filled with a stationary phase and a mobile phase. Gas-liquid chromatography and liquid-liquid chromatography focus on separating mixtures based on their physical properties, while paper chromatography utilizes paper as the stationary phase to separate mixtures. Each of these different types of chromatography has unique benefits and applications in scientific research.
