Reference Chromatogram
The reference chromatogram on the Assay tab may be used to modify the library
information. Only one run can be displayed. This chromatogram does not change
when you select a different column/detector combination. It may not be the
chromatogram associated with the currently selected column/detector combination
or the library.
NOTE: Before making any changes to the assay, ensure that the displayed chromatogram
was run on the same instrument using the currently selected column.
When you save the assay, the chromatogram is also saved. When you load a new
assay, SiteChart will try and load the analysis file as well. If it cannot be located,
then a message is displayed and the remaining assay information is loaded.
View Pop-up Menu
A pop-up menu, with the View menu options, is displayed by moving the mouse
into the graph area and clicking the right mouse button (right-clicking).
The Pop-up menu has the following functions:
Turn the Grid on or off.
The grid makes it easier to estimate retention times and peak heights from the
chromatogram.
Smooth the chromatogram by the required number of Points so that low
concentration peaks can be more easily integrated.
After the chromatogram has been smoothed, you can re-integrate it.
You can change the Integration Method and Reintegrate the chromatogram.
This is useful if you need to store peaks that are not well integrated.
Change the Font size of the text on the chromatogram.
You can set the font to Small , Medium , Large or Automatic . Automatic
adjusts the font size to fit the current view options.
