Adjusting the Baseline

 

 

Parameter

Description/Specifies

 

 

Peak Width

Set Peak Width according to the data you are correcting:

(at half height)

• For best results, set to the peak width at half height

 

(continued)

of the narrowest peak. However, smaller peak width

 

values increase processing time.

 

• If peak width varies across the spectrum, set to the

 

average peak width.

 

• If peaks are narrow relative to the baseline region

 

you are correcting, set a larger value (for example,

 

10 times the width of widest peak) to increase

 

processing speed.

 

• If the baseline changes sharply across the spectrum,

 

set a smaller value closer to the narrowest peak

 

width.

 

• If the baseline is broad or gently sloping, set a larger

 

value, for example 10 to 20 times the width of the

 

actual peak width.

 

To determine the number of points across a peak, change

 

the trace display from Line to Vertical Bars (select

 

Graphic Options from the Display menu, click Graph #

 

Setup and change Line Type). Each vertical bar

 

represents one data point. For more information, see

 

Section 1.4, Customizing the Data Explorer Window.
