Chapter 2 Using Chromatogram and Spectrum Windows

2.4.10 Viewing Trace Labels

 

 

 

The Data Explorer software includes a label in the trace

 

 

 

header to identify the type of data displayed.

 

 

 

 

 

 

 

NOTE: Trace labels are applied by the software and cannot

 

 

 

 

 

 

be removed.
