Chromatogram Zooming and Scrolling

The following mouse actions are possible for the chromatogram display window:

Action Effect of Action

Left mouse button click

and drag a selection.

Expands selected section of chromatogram to fill the

entire window.

Left mouse button

double click.

Zooms to full scale.

Left mouse click and

hold

Zooms isometrically from the mouse position, or, if you

are holding the control key down, zooms out from that

point. Once PowerZooming begins, you can move the

mouse around while the mouse button is still down to

change the point at which you are zooming

You can view other sections of the chromatogram while maintaining the same

zoom level by scrolling. Scroll bars are shown only if the time or amplitude range

of your zoomed view is less than the maximum time or amplitude range of the

chromatogram. Scrolling horizontally lets you see sections of the chromatogram

earlier or later than the current section. Scrolling vertically lets you see sections

of higher or lower amplitude.

You can scale vertically using the Attenuation Control to the right of the

chromatogram display window. This adjusts the amplitude range on a logarithmic

scale. When using the attenuation control, the lowest point of the active trace is

fixed, and the amplitude range is adjusted to a smaller range as you slide the

position indicator up and to a larger range as you slide it down.

You can zoom in the amplitude and time axes in the same way as you do in the

chromatogram display window. You can select a rectangular section of the axis,

PowerZoom, and double click in the axis. These actions zoom just like they

would in the chromatogram display window, except that only the amplitude

scaling is affected when zooming in the amplitude axis and only the time scaling

is affected when zooming in the time axis.

3800 Setup Dialog Box

This dialog box shows the hardware configuration reported by the 3800 GC. This

configuration is compared to and must match the configuration in the Method

when it is activated.
