A gas chromatograph is a chemical analysis instrument for separating chemicals in a complex sample. A gas chromatograph uses a flow-through narrow tube known as the "column", through which different chemical constituents of a sample pass in a gas stream (carrier gas, "mobile phase") at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the "stationary phase".
