3. Select the amount of smoothing to be applied.
The signal will be smoothed and the modified chromatogram is displayed.
None
provides no smoothing and
15
provides the maximum smoothing. If you
select
15
, SiteChart averages 7 points before and 7 points after every point on
the baseline.
4. From the View menu, select
Re-integrate
.
If signal noise was affecting integration, signal smoothing will lead to more
accurate integration.
5. Annotate the notes for this chromatogram, to show that the original file has
been modified, and then save it.
You can always return to the original chromatogram by setting smoothing to
None
.
Status Block
This command enables/disables the status block. The
status block
displays the
signal level and the slope of the signal at a time defined by the position of the cross-
hair. The cross hair does not need to be directly on the signal.
Font Size
Selects the font size for the labels on the graph.
Automatic
is always readable. It
adjusts the font size with the current view.
Small
,
Medium
, and
Large
allow you to
customize the displayed font as required.
Re-integrate
The
Re-integrate
command recalculates the area of the peak using the new
integration parameters or new library information.
When you re-integrate, the integration method from the current assay is used. If an
assay has been loaded from another instrument, the serial number will not
correspond to the analysis. SiteChart will display a warning message. You can
override this message, but use caution. The reported results may be invalid.
