2 Installation
The following is a detailed description of the TitrIC 2 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 exclusively to the version in which the 855 Robotic Titrosampler is located
at the left-hand side of the system.
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.
Do not screw the titration head (6.1462.070) onto the Swing Head!
The Sample Rack supplied is screwed onto the 855.
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.
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.
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.
2.2 712 Conductometer (2.712.0010)
The 712 Conductometer is placed directly to the right of the 855 Robotic Titrosampler and behind the
stand support. For detailed information about the usage check the Instructions of Use of the 712. It is
recommended to carry out the calibration of the cell constant manually and before tiamo is started up.
Consult thereto the Installation Instructions of the 712 Conductometer, chapter 4.4.3. But firstly the
712 has to be registered in the configuration of tiamo so that the calibration can be stored. Thereto the
calibration should be made later when the 712 is registered and tiamo shut down.
2.3 Bottle holder (6.2061.010)
Directly to the right of the 712 Conductometer, place the bottle holder for the bottles with the titration
solution (0.1 M HCl, at the rear, with 20 mL Dosing Unit and 800 Dosino) and the acidification solution
(1 M HNO
3
, at the front, with eluent bottle attachment).
2.4 Dosino holder (6.2055.100)
The Dosino holder (6.2055.100) is placed in front of the bottle holder and the 712 Conductometer; the
50 mL (6.3032.250) and 10 mL (6.3032.210) Dosing Units are screwed onto this holder at a later
stage.
2.5 861 Advanced Compact IC (2.861.00x0)
Place the 861 Advanced Compact IC for cations (2.861.0010) to the right of the bottle holder. To the
right of the 861 for cations, place the 861 Advanced Compact IC «MSM» for anions (2.861.0020). The
two instruments can already be installed. Please consult the Instructions for Use for the Advanced
Compact IC instruments.
