Connections On A 2-Position, 10-Port Column Switching Valve - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

4.8.2 Connections on a 2-position, 10-port Column Switching Valve

Fig. 27 shows the connections on a 2-position, 10-port column switching valve for tandem
operation.
For tandem mode, the UltiMate 3000 system must include one dual gradient pump or two
single gradient pumps with identical flow rates, two columns, and one 10-port column
switching valve. Running the UltiMate 3000 system in this configuration allows increasing
the sample throughput considerably, typically by 50 to 100%. For more information about
tandem operation, see the Chromeleon Help.
Fig. 27: Example for the connections on a 2-position, 10-port column switching valve
To realize the setup shown in Fig. 26 with a 10-port column switching valve, follow these
steps:
1. Connect the capillaries to the same ports as on the 6-port valve (identical port
numbers).
2. The 6-port valve has a direct fluid connection between ports 1 and 6. To achieve this
fluidic connection for the 10-port valve, install an additional capillary between ports 7
and 10 (inner diameter of the capillary: 0.13 mm for micro setups; 0.25 mm for
analytical setups).
3. Ports 8 and 9 are not used for this setup. Thermo Fisher Scientific recommends
connecting these ports with an additional capillary or closing them with a plug.
