The thickness correction
algorithm removes pathlength variations from spectra. The user needs to
select a peak and a baseline. The algorithm offers various methods, please
review the chapter thickness
correction in the mathematics section for details.
The general thickness correction workflow consists of selecting the
thickness band baseline and the actual thickness band. The thickness band
baseline line will then be corrected by a two-point
baseline algorithm with the selected parameters and the thickness
correction will be performed. Selecting the parameters is performed as
follows:
To apply thickness correction using the menu command, please follow
the instructions below:
Activate the
2D data object you like to correct.
From the Mathematics
menu, select the Thickness correction
command from the Spectrum Arithmetics
submenu.
In the Mathematics
tab, select the parameters for thickness band baseline and the
thickness band by entering numerical values.
Alternatively, adjust parameters by using the vertical
selection lines or rectangle areas in the spectrum view.
What are different selection tools good for?
Distinct vertical lines select single points in the spectrum to define
peaks or the borders of peak areas. Colored rectangles define a range
of points from which the actual anchor point will be calculated by the
selected method (average, minimum, maximum). Please review details in
the chapter thickness
correction in the mathematics section.
