4.4.3 Chromatogram Types
The following types of chromatograms are provided.
1) Latest chromatogram
This is the chromatogram currently being measured. One latest chromatogram is provided
for each detector (latest chromatogram 1-1 to 3-2), and the update cycle is 1 second.
2) Previous chromatogram
This is the chromatogram measured the last. One previous chromatogram is provided for
each detector (previous chromatogram 1-1 to 3-2).
3) Saved chromatogram
This chromatogram is saved by the user to the GC8000 main body. A maximum of 20
chromatograms per system can be saved as “saved chromatogram”. If the analysis cycle is
30 minutes or more, the number of chromatograms that can be saved decreases.
4) Baseline chromatogram
This chromatogram is saved by the user to the GC8000 main body as “baseline
chromatogram”. One chromatogram per system can be saved as “baseline chromatogram”.
5) History chromatogram
This chromatogram is automatically saved to the GC8000 main body or PCAS. Saved to
the GC8000 main body is the “history chromatogram” for the past one week for six detectors
(for the past six weeks if there is only one detector). To PCAS, all the chromatograms in the
past two months can be saved. This denotes that, if saved once per ten analyses, all the
chromatograms in the past one year can be saved.
