Agilent GC systems are known for their reliability, ruggedness, and long life. The Agilent 6890 is a state-of-the art gas chromatograph that provides superior performance for all applications. Key to its performance is the use of advanced electronic pneumatic control (EPC) modules and high performance temperature control. Each EPC unit is optimized for its intended use with a specific inlet and detector option. Temperature control of the 6890 oven allows for fast and precise temperature ramping. Overall thermal performance provides optimal chromatography including peak symmetry, retention time repeatability, and retention index accuracy. The combination of precise pneumatic control and accurate temperature control leads to outstanding retention time repeatability, the basis for all chromatographic measurement.
Agilent 6890 Thermal Conductivity Detector (TCD)
• Universal detector responds to all compounds, excluding carrier gas
• Single-filament, single-column design
The Agilent TCD consists of an electrically heated filament in a temperature-controlled cell. Under normal conditions there is a stable heat flow from the filament to the detector body. When an analyte elutes and the thermal conductivity of the column effluent is reduced, the filament heats up and changes resistance. This resistance change is often sensed by a bridge circuit which produces a measurable voltage change. The column effluent flows over one of the resistors while the reference flow is over a second resistor in the four-resistor circuit. The Hewlett Packard 5890 TCD can be used in the analysis of permanent gases (argon, oxygen, nitrogen, carbon dioxide) because it responds to all of these pure substances.
