This manual describes the use of the Agilent LTM Series II Rapid Heating/Cooling System (RHC) for Agilent 7890A gas chromatograph (GC). The system can be used to quickly heat and cool Agilent 7890A GC columns to improve run speed and reduce sample analysis time.
The Agilent Low Thermal Mass (LTM) Series II Rapid Heating/Cooling System is designed to enhance the column temperature programming capabilities of the Agilent 7890A Gas Chromatograph. The system allows for fast ramp temperature programming by packaging capillary GC columns into LTM column modules that mount outside the conventional GC oven, utilizing resistively heated wire and ambient air cooling.
The LTM system is compatible with Agilent 7890A GCs with firmware revision A.01.12.1 or greater.
The LTM oven door accepts up to four LTM column modules.
