2.4 Connecting the tubing
2.4.1 Connection to injection valve with PEEK capillaries
For the pressure range 0 … 25 MPa (0 … 250 bar), it is recommended to
use 6.1831.010 PEEK capillaries, a 6.2620.150 Pulsation dampener
(see section 2.3.4), and a Filter unit PEEK (see section 2.3.5) to connect
the 709 IC Pump to the injection valve of the 733 IC Separation Center.
Proceed as follows:
1 Connection to 709 IC Pump
• Cut connection capillary 22 (6.1831.010 PEEK capillary) to
the required length and equip it with connectors.
• Attach connection capillary 22 to connection 23 of the 709 IC
Pump (see Fig. 2).
2 Connection of filter unit PEEK
• Attach the other end of connection capillary 22 at the connec-
tor 45 (with filter) of the filter unit 56 (see Fig. 6).
• Connect a PEEK capillary 43 cut to the required length and
equipped with connectors to the connector 47 of the filter unit
56.
3 Installation of the capillary in the IC Separation
Center
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
4 Connection of the pulsation dampener
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
5 Connection to the injection valve
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
