761 SD Compact IC / Instructions for Use 8.761.1043

2.6.7 Connection suppressor → waste

Route the "suppressor outlet capillary for eluent ("Waste")" 44 at the rear

out of the 761 SD Compact IC into a waste container.

2.7 Installing the regenerant path

The regenerant (100 mmol/L H

) is aspirated with the peristaltic

pump from the regenerant MPak and forced into the suppressor via the

filter unit PEEK. From the suppressor, it is then routed into a waste con-

tainer (see Figure 9).

2.7.1 Fitting the pump tubing for regenerant

One channel of the two-channel peristaltic pump is used to pump the

regenerant. Fit a pump tubing 61 6.1826.110 as follows:

1 Disengage the tubing cartridges

• Detach and disengage the two tubing cartridges 57 above

the pump drive 49 by pressing in the snap-action lever 59 on

the retaining bracket.

• Press the pressure lever 58 down fully.

2 Fit the couplings 60

• Fit one coupling 60 6.2744.110 onto each end of the pump

tubing 61 6.1826.110. Moistening the tip of the coupling

lightly will make it easier to slip it on.

3 Fit the pump tubing

• Insert the fitted pump tubing 61 as shown in Figure 8 into the

tubing cartridge. The left-hand stopper 62 should latch into

the corresponding fixture on the left-hand side of the tubing

cartridge.

4 Reengage the tubing cartridge

• Reengage the tubing cartridge with pump tubing 61 in the re-

taining bracket. Engage it at the left first and then press the

right-hand side down until the snap-action lever 59 engages.

Ensure that the pump tubing is not kinked when doing this.

• Leave the other tubing cartridge outside. It is fitted with the

pump tubing for the sample path (see Section 2.8.1).
