Gas Chromatography

Gas chromatography is a technique used to separate and analyze compounds in a mixture. In this process, a sample is vaporized and carried by an inert gas through a long, thin tube called a column, which is coated with a special material. Different compounds in the sample move at different speeds based on their chemical properties, causing them to separate as they travel through the column. As they exit the column, they are detected and recorded, allowing for the identification and quantification of each component. This method is widely used in fields like chemistry, environmental testing, and food safety.
