The Hewlett Packard HP 5890 Series II Gas Chromatograph is a chemical analysis instrument used to separate chemicals in a complex sample. This instrument uses a flow-through, narrow tube, known as the column, through which various chemical components of a sample are passed in a gas stream (carrier gas, mobile phase); the components move at different speeds depending on their chemical and physical properties as well as their interaction with a specific column filling, the stationary phase. As the chemicals emerge from the end of the column, they are detected and identified electronically. The function of the stationary phase in the column is to separate different components so that each exits the column at a different time (retention time). Other parameters that can be used to change the order or retention time are the flow rate of the carrier gas and the temperature. This system is characterized by: Compatibility with ChemStation. Schedule operation. Diagnostic function. Electronic pressure control option. Power Failure Recovery Labprocure is responsible for this device.
