Agilent 7890A Gas Chromatograph/mass selective detector (GC/MSD)
System Information General Description: 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) at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the stationary phase.
As the chemicals exit 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, causing each one to exit the column at a different times. Other parameters that can be used to alter the order or time of retention are the carrier gas flow rate, column length and the temperature. Capabilities:
5th-generation electronic pneumatics control (EPC) and digital electronics set a new benchmark for retention time locking (RTL) precision.
Faster oven cool down, robust back flush capability, advanced automation features and faster GC/MSD oven ramps let you get more done in less time, at the lowest possible cost per sample.
Powerful, chromatographer-friendly software simplifies method setup and system operation and minimizes training time. Practical, time-saving design features speed up and simplify routine maintenance.
