One example of this tube-conserving option's usefulness is to
collect like eluate from multiple, identical samples while
repeating the same liquid chromatography method. Because the
peaks elute the same each time, greater volumes of pure com-
pound can be collected in a tube.
Next – The Next option continues with the next available tube at
each restart.
Skip – The Skip option skips one tube and continues with the
following tube at each restart. The empty tube helps you locate
the sets of tubes for each restart.
The fraction collector can control an external pump from pin 2 of
the Pump connector. This signal is used to pause the pump
during tube changes.
Touch the Pump Control icon to view the current setting.
the external pump will continue to operate during tube
changes. The icon with the "0" indicates that the fraction
collector will send a pause signal from pin 2. Touch the icon
to toggle the state.
The fraction collector can receive an analog peak signal from an
external detector. The fraction collector receives this signal at pin
8 of the Detector connector.
When using this feature, set the analog peak voltage scale to the
range of the detector signal, either 1000 mV, 100 mV, or 10 mV.
Touch the Analog Peak setting icon to view and select the range
using the Up and Down Arrows.
Choose the voltage that corresponds to your detection device's
100% signal output. If your detector does not scale its output to
one of the options, choose the option just above your highest
expected peak voltage.
If you select the External option, the fraction collector will ignore
the signal at pin 8 and monitor the TTL signal at pin 2 instead.
The fraction collector begins cutting peaks when an active low is
present.

The icon with the "1" (left) indicates that
the fraction collector will not send a
pause signal from pin 2. In this state,
