The Hewlett Packard HP 5890 Series II Gas Chromatograph is a chemical analysis instrument used for separating chemicals in a complex sample. This instrument 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); the constituents move at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the stationary phase.
