rather than a pan function.)
The gradient plot area also provides a convenient method to
edit the gradient curve. You can click and drag any of the
points to change the shape of the curve and use the buttons
at the bottom of the plot area to insert and delete points.
For complete instructions on defining gradient curves, see
Section 5.3.3 Defining a Gradient.
MS – The MS button displays the current mass spectrum on
PurIon systems. This spectrum hides the flow rate and solvent
selection controls. Pressing the MS control again causes the
spectrum to disappear. When the spectrum is displayed, touching
the chromatogram at any point prior to the current elution time
displays a spectrum at that point in time; the elution time corre-
sponding to the spectrum is displayed under the spectrum.

completion of the separation and saves the spectrum
at a point for inclusion in the run report screen. Up to
4 spectra can be saved in a run report. The button
depicted with a triangle pointing down allows a user
to cycle through saved spectra.
· The ± button displays the positive or negative ion
spectrum (PurIon S and PurIon L systems only). A
dot in the button indicates whether the positive or
negative ionization spectrum is displayed.
UV – The UV (UV-Vis on ACCQPrep systems with a UV-Vis
detector) button displays the UV spectrum on systems. This
spectrum hides the flow rate and solvent selection controls.
Pressing the UV control again causes the spectrum to disappear.
When the spectrum is displayed, touching the chromatogram at
any point prior to the current elution time displays a spectrum at
that point in time; the elution time corresponding to the
spectrum is displayed under the spectrum. The L
button shows the current spectrum. The A
saves the spectrum at a point for inclusion in a run report screen.
Up to 4 spectra can be saved in a run report. The button depicted
with a triangle pointing down allows a user to cycle through
saved spectra.
Run Settings – •
• Column — Select the name of the column used on the
system. A second level menu will allow you to select
from methods already associated with the selected
column. If the system has a Column Selector Valve
Module, this control allows you to select the column that
will be used for the separation.
• Sample Name — The sample name is a text entry box in
which you can label the run. Type a unique descriptor.
PeakTrak saves the run information under this name.
Therefore, PeakTrak cannot accept any characters that
are reserved by the operating system (* ? / \, etc.).
