g. Attach the eCord fob to the receptacle on the side of the column
heater.
h. Close the column heater door.
Installing the optional column stabilizer assembly
The column heater's optional column stabilizer reduces sensitivity to ambient
temperature swings by transferring heat (via conduction) from the column
heater's film element through the thermal gasket to the column inlet tubing.
The looped tubing path reduces dispersion while ensuring maximum surface
area contact between the tubing and the column tray, maximizing heat
transfer to the mobile phase.
The passive column stabilizer provides thermal equilibration by heating the
incoming mobile phase and injected sample to the specified column
temperature before they enter the column.
You cannot use the active preheater and the passive column stabilizer
Note:
simultaneously; choose the preheater type that best suits your application.
