After setting of the parameters, the fraction collection is started by pressing the
START
button.
The collector will take the number of samples as programmed under the
NUMBER
setting
and will stop for the time programmed under the
PAUSE
setting. This cycle will go on until a
STOP signal will be encountered. The LAMBDA peristaltic pump is activated automatically
only during fraction collection.
When the fraction collection is controlled from the panel (i.e., not by remote
control signal) the fraction collector will collect the number of
fractions/samples introduced in the parameter
NUMB
of duration
TIME
or
volume
COUNT
(if a drop counter or LAMBDA pumps are used), followed
by the PAUSE, if a PAUSE was set.
Then, the fraction collector will repeat this till the
STOP
signal is
encountered (i.e., STOP is pressed or the fraction collector is stopped by
the end magnet). This collection mode allows for e.g., a line washing step
before the relevant fraction is taken.
