1.6.2 Start button (F2)
A cycle may be executed by pressing the button labelled
Start,
which is then re-
labelled
Stop
.
The cycle can then be stopped by pressing the same button, which
is then re-labelled
Start
.
Start
and
Stop
may also be actioned by toggling F2.
When a cycle is started, the analyser waits for the ending time of the first peak
and begins its peak detection between the starting time and the ending time. If a
peak is found, the peak that is detected and used for integration is presented in
yellow below the raw signal coming from the detectors.
During the cycle, the progress bar rises with time. The bar starts at the left and
ends at the right. The cycle length can be set in the
CONFIGURATION-
CYCLE
menu. During a peak, a green circle appears at the corresponding peak
of the upper grid alarm column (Al). When the peak detection process is
completed, the peak area is converted into the process value and displayed in the
grid beside the peak name in the value field. Then the analyser waits for other
peaks and applies the same procedure.
The cycle continues even if you exit the
REAL-TIME
CHROMATOGRAM MENU
.
It is not recommended to
Stop
a real time chromatogram during a
cycle.
1.6.3 Injection Mode
Use the
Injection Mode
radio control to select one of two injection modes. The
Manual
mode executes one cycle after the
Start
button is pressed. The
Automatic
mode restarts new cycles until the
Stop
button is pressed or the
Manual
mode is selected.
1.6.4 Injection Status
The
Injection Status
radio control enables sample injection when the
ON
radio
control is selected and disables sample injection when the
OFF
radio control is
selected.
1.6.5 Enhanced View (Ultra only)
The
Enhanced View
radio control enables the chromatogram view to focus
between the Baseline and the Saturation line (see Figure 15). This enables the
user to clearly view the peaks on the chromatogram.
