                The TitrIC 2 System with two 861 Compact ICs and an 855 Robotic Titrosampler
The TitrIC 2 System is used for the fully automatic analysis of water samples using direct measure-
ment, titration and ion chromatography. The following measured values are determined in a very short
time: temperature, conductivity, pH, acid capacity and, in parallel, the concentrations of the individual
anions and cations. Further Metrohm instruments can be incorporated in the existing system at any
time and used to measure additional parameters.

Analytical sequence
      1.      Conductivity is measured in the sample vessel on the sample changer.
      2.      First sample transfer to the two 861 Advanced Compact ICs.
      3.      The IC measurements are started automatically.
      4.      Second sample transfer to the external cell of the 855 Robotic Titrosampler.
      5.      Temperature, pH and acid capacity (p and m values) are determined.
The whole procedure is controlled by the TitrIC software: The user enters the sample position and
sample identification, IC system and tiamo method, after which TitrIC transfers all the relevant
information to tiamo and IC Net. When the measurement has been concluded, TitrIC automatically
generates a joint report containing all results. This report can be printed out or produced as an Excel
table.

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 HNO3, 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.

                      Connections on the bottoms of the 10 mL and 50 mL Dosing Units


         Port 1 is used for emptying the Dosing Units into the waste canister.
         Port 2 is used by the 50 mL and 10 mL Dosing Unit for taking in the sample via the titration
         arm.
         Port 3 is used for sample transfer to the IC system. The transition from M6 to the IC screw
         size (1/16 in.) is achieved with the 6.2744.080 adapter.
         Port 4 is used for the 50 mL and 10 mL Dosing Unit. This requires a coupling between Luer
         and M6: The PEEK connection (6.5620.000) is attached to the Luer connection on the bottom
         of the Dosing Unit. With the 50 mL Dosing Unit this port is used to realize «liquid handling» to
         the external cell; in contrast with the 10 mL Dosing Unit it is used to aspirate the nitric acid for
         acidification.
Once the tubing connections have been made, the Dosing Units are attached to the Dosino holder
(6.2055.100) with the screw attachment and the distance ring of the Connecting Set for Dosing Unit
(6.5620.000).

6.2.7 Methods
The following seven methods are provided:
                            With this method all the parameters possible with the standard instruments
         TitrIC 2 - complete run:
         are measured and the IC measurement is initiated.
         TitrIC 2 - titration and measurement: Only titration and direct measurements are carried out; the IC
         measurements are not initiated. In TitrIC under Settings/IC Net settings the IC Anions and IC Cations
         have to be deactivated, or the method is started up only from tiamo.
                                                  This method is used for preparing all titration instruments,
         TitrIC 2 - preparation of titration equipment:
         i.e., rinsing the tubing connections of the Dosing Units with reagents or deionized water and
         rinsing the external cell. Start this method only from tiamo – not from TitrIC!
         TitrIC 2 - IC calibration - anion & cation: This method is used for calibrating the IC measurements
         with standard solutions without having to carry out the titration part of a typical TitrIC
         measurement; this means that a lot of solution can be saved.
         TitrIC 2 – semi automated pH calibration: With this method the pH electrode is calibrated automated;
         the buffer solutions are poored into the titration vessel. Start this method only from tiamo – not
         from TitrIC!
         TitrIC 2 - pH calibration: Here the Aquatrode is taken out of the titration vessel and placed into the
         buffer solutions. Start this method only from tiamo!
         TitrIC 2 - titer determination:   This method is used for the titer determination. Start this method only
         from tiamo!
         An automated conductivity cell calibration method for tiamo can be delivered if desired
         (titric@metrohm.com); it is recommend to do it manually.



    Import: Click on Method at the left, then select under File / Method manager… / Edit          / Import…   in the
    directory C:\Program Files\Metrohm\tiamo\methods_titric all methods and click on <Open>.

         Note!
         Alterations of these methods should only be carried out by a person at the Administrator level
         and who is thoroughly familiar with tiamo. Never forget that in TitrIC this new method must be
         selected in the sample table under Methods tiamo.

6.2.8 Configuration of the export template
Export template: tiamo must transfer its results to TitrIC in a particular way, which means that the
export template must be generated exactly in the following form:
Under Database / Tools / Templates / Export templates / New enter the following:




                                    Configuration of the export template in TitrIC

then click on Select fields and enter the following:




                                        Input window for the export template
The entry Start counter is obtained at the left by clicking on Determination/Identification, ID1.Name and ID1.value
are obtained at the left by clicking on Sample / Identifications, RS0x by clicking on Results / RS0xxx. By
clicking on the upper double arrow in the center the entries can be moved to the right. Of course
another number of results than five is possible.

    Shut down tiamo 1.1 !

6.3 Configuration of IC Net
   Start IC Net 2.3

         Under     Options / Global Preferences the following must be marked: under If method changed - Don’t ask
         to save   and System file overwrite - Always.
         With the TitrIC software predefined IC systems are also installed. These are found under
         C:\Program Files\Metrohm\IC Net 2.3\IC Net\Systems\Anion\anion.smt and C:\Program Files\Metrohm\IC Net
         2.3\IC Net\Systems\Cation\cation.smt. Open the two systems, click on Control / Connect to workplace
         and choose the right COM-Port. If you don’t know to which COM-Ports the systems are
         connected to you have to try out until you have communication between PC and the 861. Work
         should always be carried out with these systems, as otherwise the result transfer to TitrIC will
         be disturbed. This is why, if the systems have to be altered, the existing system is always
         altered and saved under the same name.
         The suppressor step is not made at the start of the measurement in the usual way, but with Fill
         directly after the end of the chromatogram. These means that after long pauses between
         measurements the suppression may no longer function. This is why after longer pauses you
         should carry out a suppressor step manually and ensure that the injection valve is in the Fill
         position.
         Depending on the application and column it may be necessary to adapt the time program in the
         IC system: Inject should always be carried out right at the start (0.10 min) of the time program,
         Fill right at the end. In this way you can start to measure with a stable baseline immediately
         after the sample loop has been filled by the Dosinos.
         If a calibration is carried out later and the new calibration data are to be applied to a sample that
         has already been measured then this is possible by using TitrIC – see the online help of the
         TitrIC software under Database / Recalculate / Recalculate for the results of several samples.

   Shut down IC Net 2.3



6.4 Configuration of TitrIC
   TitrIC is started (tiamo and IC Net are started automatically at the same time)

         All paths have already been entered as defaults and the system is ready for work. If other paths
         have been used instead of the default paths then this must be altered in the corresponding
         dialog under Workplace / Settings / ….
         TitrIC starts tiamo and IC Net at the same time. However, the tiamo window is not visible, but
         can be brought to the foreground in TitrIC via View / Show tiamo.
         If TitrIC is shut down then tiamo will also be shut down automatically – but IC Net must always
         be shut down individually. Always shut down TitrIC as the first program! If tiamo is accidentally
         shut down first then TitrIC is also no longer visible; the program will continue to run in the
         background. It can then be shut down with a right-hand click on an empty position in the Taskbar
         and a left-hand click on Task manager / Processes / TitrIC.exe / End process.
         For further information please consult the TitrIC online help (? / Show Help) or contact the
         responsible person at your local Metrohm agency. You can also report your problems to the
         following support email: titric@metrohm.com.



                           Always start and shut down TitrIC first!
