Chapter 5 Examining Spectrum Data

General guidelines for setting parameters

Refer to the following table to determine how to set Advance Baseline Correction parameters and obtain the desired baseline correction.

Condition

 

Set Parameters To

 

 

 

Baseline follows a rising peak cluster

Peak Width— Average peak width

 

Flexibility— 0.5

 

Degree— 0.5

Baseline is gently curving

Peak Width— 10 to 20 times peak width

 

Flexibility— 0

 

Degree— 0.5 (decrease further to raise

 

 

the baseline)

Baseline rise should be ignored and

Peak Width— Half of the width of the

treated as signal

 

cluster to correct (in the illustration

shown, if the width of the cluster is 200,

 

 

set Peak Width to 100)

 

 

 

Flexibility— 0
