Description

 

 

 

 

 

 

 

 

 

Detection Ranges

Specifies one or more non-contiguous m/z ranges for peak

 

 

 

detection. You can set parameters for each range

 

 

 

independently.

 

 

 

 

You select a range in the Detection Ranges list box by

 

 

 

 

 

single-clicking the range number.

 

 

 

 

To add a detection range, do one of the following:

 

 

• Select an existing range, then click

. This creates a

 

 

new range with boundaries ranging from the end of the

 

 

existing range to the end of the trace. If the existing

 

 

range ends at the end of the trace, the region of the

 

 

existing range is split in half between the existing range

 

 

and the new range.

 

 

 

 

• Double-click an existing range to manually enter lower

 

 

and upper boundaries.

 

 

 

 

• Select a range in the dialog box, then click-drag the

 

 

X data cursors labels in the trace to set the lower and

 

 

upper boundaries.
