•Baseline offsetting. In some situations that involve TCD detectors the baseline may be displayed either too high on the graph, in which case the tops of the peaks are cut off, or too low on the graph, so that the bases of the peaks are cut off. If this occurs it is possible to offset the baseline either up or down so that the entire peak can be displayed on the graph. This offset will be applied to all traces—live, archived and saved—that are displayed thereafter. For more information, see “Viewing raw data” on page 2-38.

•Microsoft Excel-based Parameter List. The Parameter List has been expanded to offer seven pages of information, and is Microsoft® Excel- based to allow for access outside of MON 20/20. The document can be imported to and exported from GCs. For more information, see “Working with the parameter list” on page 5-10.

•Optional Foundation Fieldbus variables. If your GC is installed with a Foundation Fieldbus, you can map up to 64 GC variables to monitor using the AMS Suite. For more information, see “Mapping Foundation Fieldbus variables” on page 4-98.

•Optional local operator interface (LOI) variables. If your GC is installed with an LOI, you can configure up to 25 GC parameters to monitor using the LOI’s Display mode. For more information, see “Working with local operator interface variables” on page 4-96.

•Access to GC-related drawings such as flow diagrams, assembly drawings, and electrical diagrams.

•Validation runs. During a validation run, the GC performs a test analysis to verify that it is working properly. For more information, see “Managing Validation Data Tables” on page 4-35and “Validating the Gas Chromatograph” on page 6-7.
