1 Introduction

The present tutorial helps you to get acquainted with the operation of the

900 Touch Control. You will be guided step by step through the most

important dialog pages by using a simple pH titration as an example.

Thereby you will learn how to efficiently operate and use the 900 Touch

Control.

1.1 Structure of the tutorial

￭Setup

Preparing the titration system.

￭Basics – simple acid-base titration

Loading and carrying out methods, displaying results.

￭Additional functions – creating methods, statistics etc.

Optimizing titration parameters, calculating statistics, efficiently using

the sample table.

￭User administration

User list, login with USB flash drive or password.

Detailed information on the functioning and operation of the Titrando sys-

tem can be found in the online help and the corresponding manuals:

￭Manual for the Titrando

￭Manual for the 900 Touch Control

￭Manual for the exchange unit

￭Manual for the 800 Dosino or the dosing unit

1.2 Symbols and conventions

The following symbols and formatting may appear in this documentation:

2 Setup and configuration

2.1 Setting up the instruments

What you will need:

￭A 900 Touch Control

￭A Titrando with internal dosing drive and an 806 Exchange Unit

A Titrando without internal dosing drive, with an 800 Dosino and an

807 Dosing Unit

￭A magnetic stirrer (801 Stirrer), an 803 Ti Stand or an 804 Ti Stand with

propeller stirrer (802 Stirrer)

￭Some sample vessels

￭A pH electrode with connection cable

￭Possibly an additional 805 Dosimat with an exchange unit (e.g. 20 mL)

Possibly an additional 800 Dosino (dosing drive) with a dosing unit (e.g.

20 mL)

￭A bottle with titrant (e.g. caustic soda c(NaOH)=0.1 mol/L)

￭Possibly a printer with connecting cable

￭Possibly a balance with connecting cable

￭Deionized water (carbonate-free)

The manual for the Titrando describes in detail how to install the accesso-

ries. A few notes about this:

Titrant

During this tutorial you will carry out simple titrations. Select an acid or

base as titrant.

Sensor

Use a pH glass electrode for the acid-base titration. Do not forget to plug

the electrode cable into the connector Ind. on the rear of the instrument.

Stirrer

Connect the magnetic stirrer (801 Stirrer) on the rear of the instrument

to the connector MSB 1.

Printer

Select a printer with a USB connector. Use a commercially available USB

cable to connect the printer.

4￭￭￭￭￭￭￭￭ 900 Touch Control

Balance

If you connect a balance to the 900 Touch Control, you can transfer the

sample size per push-button from the balance to the titrator.

800 Dosino

In case you would like to automatically add an auxiliary solution to the

sample before the titration, you will also need a Dosino. Connect it to the

connector MSB 2 on the Titrando.

Samples and sample vessels

You can use sample beakers of any size. Use an acid or base as sample,

which can be titrated with the selected titrant.

Please note that the stirrer has to be connected to the connector MSB 1

of the Titrando for the following example methods. If you use a Titrando

without internal dosing drive, then you must connect the external dosing

device (here: Dosino) to the MSB connector of the stirrer. This way it will

be controlled like an internal dosing drive of the Titrando, i.e. as dosing

device 1.
