1 Introduction
1.1 Instrument description
The IC Conductivity Detector is an intelligent conductivity detector for
usage in the instruments of the 850 Professional IC, the 881 Compact IC
pro and the 882 Compact IC plus line of instruments.
The IC Conductivity Detector continuously measures the conductivity of
the liquid passing through and indicates these signals in digital form (DSP
– Digital Signal Processing). The conductivity detector exhibits outstanding
thermal stability and thus guarantees reproducible measuring conditions.
The IC Conductivity Detector can only be used together with the IC instru-
ment. The software MagIC Net automatically recognizes the IC Conduc-
tivity Detector and checks its functional readiness. It controls and monitors
all the instruments connected, evaluates the measured data and adminis-
ters it in a database. The operation of MagIC Net is described in the online
help and in the tutorial for MagIC Net.

1.3 Intended use
The IC Conductivity Detector can only be used together with an IC instru-
ment. It is used for the precise measurement of the conductivity during
the ion chromatographic determination of cations and anions.
As the corresponding IC instrument, the IC Conductivity Detector is also
suitable for processing chemicals and flammable samples. The usage of
the IC Conductivity Detector therefore requires that the user has basic
knowledge and experience in the handling of toxic and caustic substan-
ces. Knowledge with respect to the application of the fire prevention
measures prescribed for laboratories is also mandatory.

1.5 Safety instructions
1.5.1 General notes on safety
WARNING
This instrument may only be operated in accordance with the specifica-
tions in this documentation.
This instrument has left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the
instrument, the following instructions must be observed carefully.
1.5.2 Electrical safety
WARNING
Only personnel qualified by Metrohm are authorized to carry out service
work on electronic components.
WARNING
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.

2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The instrument is supplied in highly protective special packaging. Keep this
packaging, as only this ensures safe transportation of the instrument.
2.1.2 Checks
Immediately after receipt, check whether the shipment has arrived com-
plete and without damage by comparing it with the delivery note. In the
case of damage during transportation, see the notes in chapter 7.2War-
ranty (guarantee); page 19.
2.1.3 Location
The IC Conductivity Detector is designed for usage in the detector cham-
ber of the IC instruments. For the location, the same conditions apply as
for the IC instrument.
2.2 Inserting the detector
The IC Conductivity Detector is inserted into the instruments from the
rear.
Figure 3 shows how the detector is inserted into an 850 Professional IC
instrument within 6 simple steps. Inserting the detector into an 881 Com-
pact IC pro or 882 Compact IC plus instrument is carried out analogously.

NOTE
With the instruments of the 850 Professional line of instruments, up to
two detectors can be placed and connected.
Placing the detector in the instrument
1Removing the knurled screws
￭Unscrew knurled screws on the rear panel.
￭Optional with 850 instruments: Remove the handle if it is still fas-
tened to the instrument.
2Removing rear panel
￭Remove rear panel.
3Positioning the detector
￭Put the detector through the opening and position it on the sup-
port surface intended for this purpose and slide it as far as the
limit stop to the front.
4Replacing rear panel
￭Insert the detector cable in a cable feed-through on the rear
panel.
￭Place the detector outlet capillary in a suitable capillary feed-
through.
￭Replacing the rear panel.
The detector cable (3-1) and the detector outlet capillary (3-2)
should freely hang out of the cable or capillary feed-through.
5Tightening the knurled screws
￭Optional with 850 instruments: Reattach the handle higher up
and use it as a holder for MPaks.
￭Tighten the knurled screws.

2.3 Connecting the detector
Connecting the detector cable and the detector outlet
capillary
CAUTION
The instrument must be switched off when connecting a detector.
1Connecting the detector
￭Connect the detector connection cable (3-1) to the detector con-
nection socket Detector 1.
NOTE
Recommendation: In AnCat systems with 2 detectors: anions to
Detector 1, cations to Detector 2.
2Connecting the detector outlet capillary
￭Guide the detector outlet capillary (3-2) into a sufficiently large
waste container and fasten it there.
NOTE
The detector outlet capillary must be free of blockages (the mea-
suring cell is tested to 5 MPa = 50 bar backpressure).
NOTE
The detector outlet capillary must not be shortened!
Shortening the detector outlet capillary leads to increased noise!

2.4 Connecting the detector inlet capillary
Depending on the equipment of the IC instruments the detector inlet
capillary is connected differently:
￭With instruments without suppression, directly to the separation col-
umn (see "Connect the detector inlet capillary to the separation col-
umn", page 11).
￭With instruments with chemical suppression, to the MSM or MSM-HC
(see "Connecting detector inlet capillary to MSM / MSM ‑ HC", page
12).
￭With instruments with sequential suppression, to the MCS (see "Con-
necting the detector inlet capillary to the MCS", page 12).
NOTE
In order to prevent unnecessary peak widening after separation, the
connection between the outlet of the separation column and the inlet
in the detector should be kept as short as possible.
Connect the detector inlet capillary to the separation col-
umn
1Connecting detector input
￭Fasten the detector inlet capillary (4-1) on the output of the col-
umn (4-3) using a 6.2744.070 pressure screw (4-2).
