5.3.3 Displaying Chromatogram and Temperature Data
The Chromatogram window can display eight chromatograms and two temperature data.
n Displaying Chromatograms
The following chromatograms can be displayed:
Chromatogram Type Description
Latest chromatogram This is the chromatogram currently being measured, which is updated per
1 second. Latest Chromatogram 1 and Latest Chromatogram 2 represent
the most recent chromatograms of detectors 1 and 2. The sampling rate is
80 ms.
Previous chromatogram This is the chromatogram measured previously, which is updated
periodically.
Previous Chromatogram 1 and Previous Chromatogram 2 represent the
previous chromatograms of detectors 1 and 2. The sampling rate is 80 ms.
File chromatogram This is chromatogram that has been saved to a file.
Differential
chromatogram
This is the result of differences determined by comparing two
chromatograms that are displayed. Up to two differential chromatograms
can be displayed.
History chromatogram This is a previous chromatogram that has been stored in the analyzer
server.
The sampling rate is the same as that of the analyzer. History
chromatograms for GC1000 Mark II are opened from the server by
specifying the analysis start date and time. History Chromatogram 1 and
History Chromatogram 2 represent history chromatograms of detectors
1 and 2 respectively. History chromatograms allows acquisition of
temperature data and pressure data (the sampling rate is 1 s).
When displaying two differential chromatograms, specify two different chromatograms such as
“Differential Chromatogram 1” and “Differential Chromatogram 2.” You cannot specify the same
chromatograms, for example, “Differential Chromatogram 1” twice.
l For the latest chromatograms and previous chromatograms
