732 IC Detector / 733 IC Separation Center

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 2222 (6.1831.010 PEEK capillary) to

the required length and equip with the necessary connectors.

• Attach one end of connection capillary 2222 to connection 2323 of

the 709 IC Pump (see 709 Instructions for Use).

• Attach the other end of connection capillary 2222 to the con-

nector 5353 (with filter) of the filter unit 6464 (see Fig. 13).

• Attach the PEEK capillary 6565 cut to the required length and

equipped with connectors to the connector 5555 of the filter unit

6464.

2 Installation of the capillary in the IC Separation

Center

• Unscrew the four knurled screws 3737 of the bottom rear panel

3939 of the 733 IC Separation Center and remove rear panel

(see Fig. 5).

• Insert PEEK capillary 6565 from the back into the inner com-

partment of the IC Separation Center.

• Install rear panel 3939 so that the capillary is positioned in

opening 4040 „Inlet A“ or 4444 „Inlet B“ and screw on with the four

knurled screws 3737.

3 Connection to injection valve

• Connect PEEK capillary 6565 to pulsation dampener 6666 (see

section 2.6.2). Using another PEEK capillary 6565, connect pul-

sation dampener 6767 to connection "5" of injection valve 6868.

4 Mount column connection capillary

• Connect column connection capillary 6767 (ca. 20 cm of

6.1831.010 PEEK capillary) to connection "4" of injection valve

6868.
