Parameter

Description

 

 

 

 

 

 

%Max Peak Area

Specifies a percentage of the peak with the largest area as

 

 

 

the threshold value.

 

 

 

To be detected, peaks must be above this threshold and

 

 

 

above the %Base Peak Intensity value.

 

 

 

%Max Peak Area is calculated above the local baseline and

 

 

 

can compensate for problems related to a rising global

 

 

 

baseline.

 

 

 

If you override Global Thresholds by selecting Use Advanced

 

 

 

Settings (described on page 3-23),the software ignores

 

 

 

Global Thresholds and uses the %Base Peak Intensity,

 

 

 

 

 

%Max Peak Area, Minimum Area, and Minimum Intensity

 

 

 

thresholds set on the Advanced tab (described on page 3-28)
