2.2 850 Professional IC
In order to install the Professional IC you have to perform
the following steps: Remove rollers and handle, place the
detector blocks in the instrument and connect the detector
cables, remove transport locking screws, connect the leak
sensor cable, connect the drainage tubing, and set up the
eluent bottles. Please refer to the 850 Professional IC
manual for a detailed description (chapters 2.6 and 2.8).
Capillaries are connected according to the following list and
the diagram below (also see manual chapters 2.14 to 2.18)
1. Connection to the eluent bottle for anion determination
2. Capillary to anion separation column
3. MSM inlet capillary
– labeled with Eluent
4. MSM outlet capillary
– labeled with Detector, which can
be connected to the MCS or directly to the detector.
The MCS air aspiration capillary is connected to the
CO
2
-absorber cartridge.
5. Capillary from MCS to anion detector, long PEEK
pressure screws (6.2744.090) are used for the MCS
connection
6. Detector outlet capillary to waste
7. Regeneration solution aspiration capillaries (PTFE, 0.97
mm ID), connected to two bottles with ultrapure water
and 50 mmol/L sulfuric acid respectively via peristaltic
pump tubing with orange/yellow stoppers (6.1826.320)
8. MSM regeneration solution outlet capillaries
– labeled
with Waste
– to waste
9. Connection to the Eluent bottle for cation determination
10. Capillary to cation separation column
11. Capillary from cation separation column to cation
detector
12. Detector outlet capillary to waste
13. Sample inlet capillary (PTFE, 90 cm, d=0.25 mm),
connected to the anion valve (position 1)
14. Optional sample degasser
Capillary connection (PTFE, 40 cm, d=0.5 mm) between
anion valve (position 2) and cation valve (position 1)
15. Connection capillary anion channel valve to cation
channel valve
16. Capillary to the waste
