2.6.5 Connection to injection valve with PEEK capillaries
For metal-free systems and for non metal-free systems in the pressure
range 0 … 25 MPa (0 … 250 bar) we recommend to use 6.1831.010
PEEK capillaries, a 6.2620.150 Pulsation dampener (see section 2.6.2)
and a 6.2821.100 Filter unit PEEK (see section 2.6.3) to connect the
709 IC Pump and the injection valve of the 733 IC Separation Center.
Proceed as follows:
For the connection of capillaries to the injection valve, use only the
6.2744.010 PEEK compression fittings. If other steel connectors are
used (e.g. 6.2620.000 and 6.2620.010), the valve connection may be
damaged!
1 Connection to 709 IC Pump
• Cut connection capillary 22 22 (6.1831.010 PEEK capillary) to
the required length and equip with the necessary connectors.
• Attach one end of connection capillary 22 22 to connection 23 23 of
the 709 IC Pump (see 709 Instructions for Use).
• Attach the other end of connection capillary 22 22 to the con-
nector 53 53 (with filter) of the filter unit 64 64 (see Fig. 13).
• Attach the PEEK capillary 65 65 cut to the required length and
equipped with connectors to the connector 55 55 of the filter unit
64 64.
2 Installation of the capillary in the IC Separation
Center
• Unscrew the four knurled screws 37 37 of the bottom rear panel
39 39 of the 733 IC Separation Center and remove rear panel
(see Fig. 5).
• Insert PEEK capillary 65 65 from the back into the inner com-
partment of the IC Separation Center.
• Install rear panel 39 39 so that the capillary is positioned in
opening 40 40 „Inlet A“ or 44 44 „Inlet B“ and screw on with the four
knurled screws 37 37.
3 Connection to injection valve
• Connect PEEK capillary 65 65 to pulsation dampener 66 66 (see
section 2.6.2). Using another PEEK capillary 65 65, connect pul-
sation dampener 67 67 to connection "5" of injection valve 68 68.
4 Mount column connection capillary
• Connect column connection capillary 67 67 (ca. 20 cm of
6.1831.010 PEEK capillary) to connection "4" of injection valve
68 68.
