Extracted Ion chromatogram, which includes only the response

or Range

from a mass window or range. For more information, see

(XIC)

Section 4.2.1, Creating an Extracted Ion Chromatogram (XIC).

 

 

Neutral Loss

Constant Neutral Loss Chromatogram, which extracts only the

(CNL)

response from a mass difference from a selected peak. For

Neutral Loss (CNL) Chromatogram.

 

 

Creating macros to combine processing functionsReturning to the original trace

You can create macros that perform multiple functions (for example, smooth and baseline-correct), then start the macro with one mouse click.

For information, see Section 6.7, Using the Macro Recorder.

Many processing functions generate a new trace. If you have Trace Replace mode set to Replace, the new trace replaces the original trace. For information on Replace mode, see Section 2.4.4, Adding Traces from the Same Data File to a Window.

To redisplay the original trace, select the trace type from the Display menu or click the corresponding toolbar button.
