7.5.1 Resizing

The main chromatogram shows the current “Zoom” region. To resize the image (or “zoom in” to a particular

region of the chromatogram), either change the axes scale in the reference chromatogram, or use the

“rubber band” controls on either chromatogram. To use the rubber band controls, click and hold the left

mouse button. Drag it across the chromatogram region. Release the mouse button and the main

chromatogram will be resized. Click on the Full View button in the toolbar to return to normal view.

7.5.2 Chromatogram Information (Values at Cursor)

The top left corner of the PostRun screen contains information about the chromatogram. The Values at

Cursor window in the upper left corner will list up to eight detector traces depending on the devices selected

in the runs device setup. The position of the vertical bar within the main chromatogram dictates the displayed

information. Run time, absorbance (AU), conductivity (mS/cm), gradient progression (%B), and the activity

trace values are displayed for each trace at the position of the vertical bar. To view the vertical bar, place the

cursor inside the main chromatogram.
