Chromatography Seals Overview

Scientists employ Chromatography as a technique to separate and analyse mixtures of substances into their individual components. It works by exploiting the varying degrees of affinity that different components have for a stationary phase (usually a solid or liquid) and a mobile phase (a liquid or gas).

As the mixture travels through the stationary phase, the individual components interact differently and thus separate based on factors like size, charge, and chemical properties.

Various fields extensively employ this method, including Chemical Processing, Biotechnology, Pharmaceutical, and Environmental Science. It serves tasks from identifying compounds in mixtures to purifying substances for further analysis.
