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 (see
Detectors section.
Figure 7
The Fraction Preview screen allows to test the fraction collection parameters
a-gainst 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. To load a chromatogram (for example a pilot run) click Load Signal.
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 the Fraction Preview screen the chromatogram
can be zoomed, the values for up and down slope can be specified and the
upper and lower threshold level can be set- up. The graphically specified
values are automatically transferred to the Peak Detector Table.
