AST
F
ORWARD
— Click this button to jump to the next
step of a run. Once you’ve started a run, the system
performs several steps. The first step is to deliver
solvents using the programmed gradient for the entire
run length. When this step is complete, the system will
enter the sample probe cleaning step.
Clicking the F
AST
F
ORWARD
button will cause the system
to skip any remaining time in the current step and
advance to the beginning of the next step.
If you have stopped the run before its programmed run
length has elapsed, the current method is modified
using the new run length. This modified method is ready
for the next run, or can be saved for future runs
Peak Collection Buttons – Three peak collection buttons
are located at the bottom of the M
AIN
window.
• A
LL
— Click this button to collect all eluent in the
fraction collection tubes. Detected peaks will advance to
the next tube automatically to maximum peak concen-
tration and purity
• P
EAKS
— Click this button to collect only eluted peaks in
the fraction collection tubes.
• N
ONE
— Click this button to divert all eluent to the
waste port. This is sometimes used to divert all peaks
except the peak of interest to waste. This action can also
be accomplished with the Initial Waste or Time
Windows functions.
Peak Collection Data – Peak Collection data is displayed in
the M
AIN
window after a run. You may also open a RUN
FILE for viewing data from previous runs. Clicking on a
test tube with the mass spectrum window displayed
displays the mass spectrum for compounds collected into
that tube (PurIon systems only). Clicking on adjacent tubes
allows a user to determine which fractions may potentially
contain impurities.
The peak collection data is displayed on the left side of the
M
AIN
window:
• Rack and tube information — Collected peaks are color
coded in the rack diagram so that you can easily locate
the peaks of interest. The tube colors correspond to the
color bars under the peaks displayed on the
chromatogram. If during the run more than one set of
tube racks was filled, use the N
EXT
and P
REVIOUS
R
ACK
buttons to view the additional racks. The table below the
rack diagram displays the peak data in tabular form.
