2 Installation
The following is a detailed description of the TitrIC 7 System's installation.
We strongly recommend that the individual steps are carried out in the order given below!
2.1 855 Robotic Titrosampler
The sample processor is placed at the side at which it is most easily accessible. Please note that the
following procedure refers to the 855 Robotic Titrosampler located at the left-hand side of the system.
ƒ On the right-hand side of the 855 Robotic Titrosampler, attach the stand support (6.2001.070)
without the horizontal brace to the tower of the 855 (hexagon screw beneath membrane pump
1). The brace will be installed later.
ƒ Do not screw the titration head (6.1462.050) onto the Swing Head!
ƒ The Sample Rack supplied is screwed onto the 855.
ƒ In the vicinity of the 855 the two canisters (standard equipment of 855) are placed on the floor:
One 10 L canister is used as a waste container, the second as a reservoir for deionized (DI)
water used for rinsing the external cell.
ƒ From the smaller opening of the canisters containing DI water, an M8 PTFE tubing connection
of suitable length is led to the connection box made of white plastic of membrane pump 1 and
connected.
ƒ From the front opening of the waste canister an M8 PTFE tubing connection of suitable length
is led directly to membrane pump 2 (black plastic) and connected.
A more detailed description is given in the instructions for use of the 855 Robotic Titrosampler.
2.2 856 Conductometer (2.856.0010)
The 856 Conductometer is placed directly at the right of the sample processor. For detailed information
about the usage check the Instructions of Use of the 856.
It is recommended to carry out the calibration of the cell constant in tiamo
TM
before measurements.
Consult thereto the Installation Instructions of the 856 Conductometer.
2.3 Bottle holder (6.2061.010)
Directly to the right of the 856 Conductometer, place the bottle holder for the bottle with the titration
solution (0.1 mol/L HCl, with 20 mL Dosing Unit and 800 Dosino).
2.4 Holder for Dosing Unit (6.2047.010)
The Dosino holder (6.2047.010) is mounted on the steel rod of the stand support attached to the 855
Robotic Titrosampler.
2.5 850 Professional IC Anion – MCS – Prep 2
Place the 850 Professional IC Anion – MCS – Prep 2 (2.850.2150) to the right of the Titration setup.
Install the 872 Extension Module below the 850 instrument by removing the bottom tray with the sensor
first. Both detectors are put into the 850. You can preinstall the whole IC system inclusively the
Metrohm Inline Ultrafiltration. The Ultrafiltration cell can be placed next to the iDetectors. The sample
inlet to the Ultrafiltration will be connected later. Please consult the instructions for use of the
Professional IC instruments for further details.
