In the case of the 733.0020 IC Separation Center with two injection
valves, it is possible to fill both sample loops from the same 788 IC
Filtration Sample Processor. For this, connection "1" of valve A (outlet
of the sample loop) must be connected to connection "2" of valve B
(inlet of the sample loop) using a 6.1803.040 PEEK capillary (15 cm).
2.3.10 Tubing connections 788 – 754 Dialysis Unit
If the 788 IC Filtration Sample Processor is used for an IC system with
sample dialysis (see
section 2.4.7 or section 2.5.8
), the peristaltic pump
at the 754 Dialysis Unit is used for sample conveying instead of the
pump at the 788 IC Filtration Sample Processor. Additionally, the ultra-
filtration cell is bridged. The tubing connections between the 754
Dialysis Unit and the 733 IC Separation Center have to be made as
shown in
Fig. 8
of the
754 Instruction for Use
. The only change concerns
the inlet of the sample, which is installed as follows:
Install a PEEK compression fitting 6.2744.010 on the inlet end of the
PTFE tubing
