5.3.5.3 Collection Windows Mode

Collection Windows mode allows you to specify periods called “windows” within the method when fractions
will be collected. Each window can have a different fraction size. During a window the Diverter Valve sends
the fluid to the fraction collector and the collector advances as programmed. Outside of the windows the
Diverter Valve sends the fluid to waste. The units used for the fraction size and Collection Windows are
either time (minutes) or volume (ml) depending upon the choice made when the method was created. Table
20 describes how to program Collection Windows Mode.

Description

Fraction Collector Table for Collection Windows Mode:
Each window in a method is shown in a scrolling list format.
The selected window is shown with an arrow (>) pointing to the
window. Use the Prev and Next keys to move the selection up
and down the list.

When the selected window is already programmed the softkeys
are as shown in the top picture and when the selected window
is not already programmed the softkeys are as shown in the
bottom picture.

The table consists of 4 columns: the window number, the start
of the window, the end of the window, and the fraction size. Up
to 50 windows can be programmed in a method and the units
will be either time (minutes) or volume (ml) depending upon the
choice made when the method was created.

•

Insert: This places a new window into the method using the
window number of the current selected window. The cur-
rently selected window and all subsequent windows have
their window number increased by one.

•

Edit: This allows the contents of the selected window to be
changed.

•

Delete: This removes the selected window from the table.
The window cannot be retrieved.

•

Add: This allows a new window to be added to the end of
the table.

•

OK: This indicates that the table is complete and returns to
the Method List.

Note: To program the Pump Table or the Alarm Table without
returning to the Method List press the Pump and Alarm keys
respectively while viewing the Fraction Collector Table.
