gas chromatographic analysis

Gas chromatographic analysis is a technique used to separate and identify different substances within a mixture. A small sample is vaporized and carried by an inert gas through a column packed with a material that interacts differently with each component. As the mixture moves through, components separate based on their affinity for the column material. Detectors then measure when each component exits the column, creating a unique pattern called a chromatogram. This process helps scientists determine the composition and quantities of substances in complex samples efficiently and accurately.
