Secondary Oven

The Secondary Oven allows for independent temperature control of the second dimension column, which decouples its performance from that of the first column. This can simplify the tuning of GC x GC chromatograms. The Secondary Oven can be run either at a lower or higher temperature than the GC oven, and is operated by the Aux 2 channel of the 6890 GC.
