Connections On A 2-Position, 6-Port Column Switching Valve - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

UltiMate 3000 Series:
TCC-3000SD and TCC-3000RS Column Compartments
To ensure proper connection, a short part of the capillary must stick out of the ferrule.
Therefore, remove the capillary from the valve to verify this. In addition, check that the
ferrule grabbed the capillary. When pulling the ferrule gently, you should not be able to
move the ferrule on the capillary.
3. Route the capillaries through the capillary guides that are provided on the left and right
of the column chamber (→ Fig. 3, page 21) into the column chamber. The connections
should be as short as possible.
4. Reinstall the drip tray of the valve if applicable.

If you have connected the inlet capillary of a column to position 6 of a 2-position, 6-port
switching valve, you must use position 5 for the outlet capillary of this column. The same
applies to valve ports 2 and 3.
