Fraction Preview
To determine the appropriate fraction collection parameters the Agilent
ChemStation provides a valuable tool that becomes accessible by pushing the
button labelled Fraction Preview Tool (Figure 12) in the Peak Detectors
section.
The Fraction Preview screen allows to test the fraction collection parameters
against an example chromatogram. It can also be used to optimize the fraction
collection parameters interactively. With the help of this tool values for up and
down slope as well as for upper and lower threshold can easily be graphically
specified. A chromatogram e.g. a pilot run can be loaded by pushing the Load
Signal button. Parameters can now be changed either manually in the Detector
Table and Timetable or graphically in the Fraction Preview screen. By pushing
the desired buttons on the right hand side of Fraction Preview screen the
