766 IC Sample Processor

2.3.8 Tubing connections 766 – 733

For transferring the sample from the 766 IC Sample Processor to the

injection valve of the 733 IC Separation Center the following tubing

connections must be made:

Pump tubings are consumable material with a lifetime which depends

on the contact pressure (see section 6.3.3). This is why the tubing

cartridges should be raised completely by loosening snap-action lever

1717 on the right-hand side if the pump is to remain switched off for a

considerable length of time (the set contact pressure remains un-

changed).

The 6.1826.0X0 pump tubing is made of PVC and must not be used

for rinsing with solutions which contain acetone. In such cases, rinse

with different pump tubing or a different pump.

Install pump tubing

• Release tubing cartridge 1313 from holding clamp 1616 by

pressing down snap-action lever 1717 and remove from

mounting pin 1212 on the 766 IC Sample Processor (see Fig.

1).

• Press contact pressure lever 1515 on the tubing cartridge down

as far as it will go.

• Insert pump tubing 1010 in the tubing cartridge 1313 as shown in

Fig. 9. The black-black stopper 3636 must click into the corre-

sponding holder on the left-hand side of the tubing cartridge.

• Place the tubing cartridge 1313 on mounting pin 1212 and press

down on the right-hand side until snap-action lever 1717 clicks

into position on holding clamp 1616. Take care that no kinks are

formed in the pump tubing.

Connection needle – pump tubing

• Mount the PEEK compression fitting 66 on one end of the

PEEK capillary 88 and the PEEK compression fitting 3434 on the

other end.

• Screw the PEEK capillary 88 with the PEEK compression fitting

66 on to the PEEK compression fitting 55 already mounted on

needle holder 44 (see Fig. 6).

• Insert PEEK capillary 88 into the guide chain 99 (see Fig. 1 and

section 2.3.8).

• Screw a coupling 3535 on to the PEEK compression fitting 3434 at

the other end of PEEK capillary 88.

• Push coupling 3535 on to the inlet end of the pump tubing 1010

(see Fig. 6).
