The following explains the elements of the Chromatogram window.
1) Caption
Displays “#Analyzer ID-GCM number (window startup status)” after a window name.
As the window startup status, “Online” or “Off-line” is displayed.
2) Legend
Displays the correspondence between pen colors and the chromatogram names
currently displayed. A chromatogram can be shown or hidden, or deleted, and the active
chromatogram can be selected in this area.
3) Enlarge/Reduce button
Use this button to enlarge or reduce X-axis scale, Y-axis scale, temperature axis, or
pressure axis.
4) Overall display area
An area displays the whole chromatogram. The portion displayed in the enlarged display
area is indicated in cyan.
5) Mouse position indication
When the mouse cursor is in the overall display area or enlargement display area, the
coordinates that the current mouse cursor indicates is displayed by “elapsed time (sec.) and
detector electromotive force (mV)”.
6) Enlargement display area
An area where a chromatogram is displayed. The selected portion of a chromatogram can
be enlarged. On a chromatogram, the gate mark, peak mark, and peak number can be
displayed.
It can also display the peak information, gate information, temperature data, and pressure
data corresponding to the chromatogram.
7) X-axis scale
Indicates the elapsed time (in sec.) of chromatogram.
8) X-axis scroll bar
Scrolls chromatogram in the X-axis direction.
9) Y-axis scale
Indicates the electromotive force (in mV) of chromatogram.
