What is an GC screen?

A GC screen, or gas chromatography screen, is a laboratory technique used to separate and analyze compounds in a mixture based on their volatility and interaction with a stationary phase. It involves vaporizing the sample and passing it through a column containing a stationary phase, where different compounds elute at different times. This method is commonly used in various fields, including environmental monitoring, pharmaceuticals, and food safety, to identify and quantify specific substances in complex mixtures.
