• P — Click this button to collect only eluted peaks in

the fraction collection tubes during a run.
• N — Click this button to divert all fluids during a
ONE
run to the waste port.
• Tube Volume — You can also specify the Tube Volume
for collected fluids. This volume can be the default
maximum volume for that tube size (Max option) as
entered in the C
ONFIGURATION
method-specific volume less than the capacity defined by
the C
ONFIGURATION
Note
The actual fraction size may be less if a newly detected peak
causes a tube change, or if you click the N
• Peak — Type or select the desired volume to be collected
in each tube when the system detects a peak.
• Non-peak — Type or select the desired volume to be
collected in each tube when peaks are not detected. This
setting allows you to conserve tubes without diverting
non-peak elute to waste. This setting is ignored when
the peak collection mode is set to Peaks or None.
Peak Detection – This section of the window contains
option buttons to enable and disable various peak detection
options. When an option is enabled, the window also allows
you to modify the setting details for that peak detection
option. All enabled options will be displayed on the
chromatogram. The options and settings for the ACCQPrep
systems, are described below.
Note
You can select up to four peak detection options on the
ACCQPrep systems,. If using more than one option, such as
λ with λ
, the system considers a peak to be present when an
1 2
option is true (a logical OR).
• λ and λ
(wavelength 1 and 2) — Enable these options
1 2
to use and configure primary and secondary wavelength
detection. λ
is set to monitor (displayed but not used for
2
peak detection and cutting) by default. When enabled,
type or select the peak detection wavelength in
nanometers, then click the D
additional settings described below.
· Slope Based — Select this option to enable
· Slope-based peak detection. When enabled, peaks
will be recorded if the slope algorithm detects a peak
similar to the Peak Width setting.
• Threshold Detection —
Threshold peak detection. When enabled, peaks will
start when the detector signal exceeds the
