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 measurement, 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 HNO

6.2.7 Methods

The following seven methods are provided:



TitrIC 2 - complete run: With this method all the parameters possible with the standard instruments

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.



TitrIC 2 - preparation of titration equipment: Th is method is used for preparing all titration instruments,

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.

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

to save

Options / Global Preferences the following must be marked: under If method changed - Don’t ask

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 s am e 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 and a left-hand click on

 For further information please consult the TitrIC online help (

Task manager / Processes / TitrIC.exe / End process.

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!
