Intended Use

®
The TitroLine 7800 is a potentiometric-/volumetric-/KF- titrator and suitable for pH-, mV-, LF, µA-, volumetric KF-
and Dead-Stop- titrations with a maximum of 50 memorisable methods.
The examples of possible use include:

Acid and base determination in aqueous solutions such as p and m value, titration of strong and weak
acids and bases

Redox titrations such as iodometry, manganometry, chromatometry, and COD determinations,
other mV titrations, e.g. chloride

Titrations using ion-selective electrodes, e.g. calcium, fluoride, copper, lead ions

Indices such as OH number, iodine number, and saponification number

Reading out and saving the calibration data from SI Analytics

Titration up to two inflection points examined as the titration of calcium and magnesium

pH-Stat titrations

Non-aqueous potentiometric titrations such as TAN and TBN

Pre-dosing with a connected piston burette

Connection and use of an autosampler TW alpha plus/TW 7400

KF titrations with 1-component KF reagents

KF titrations with 2-component KF reagents

Dead stop titrations such a bromine number and sulphur dioxide in

Connection of intelligent digital sensors (IDS
on the second digital measuring input.

Parallel recording of two measuring parameters

Compatibility with TitriSoft from Version 3.3
Further applications can be found in food technology, pharmaceuticals, biochemistry, photofinishing,
environment, quality control, and process monitoring.
In addition, the TitroLine

Manual titrations with or without calculation of the result

Dosing

Preparation of solutions
Each method allows for the setting of a variety of dosing and filling rates.
Solutions to be used:
Virtually, any liquids and solutions with a viscosity of < = 10 mm²/s such as concentrated sulphuric acid may be
used.
However, one has to avoid the use of chemicals that may attack glass, PTFE or FEP or that are explosive,
such as hydrofluoric acid, sodium azide or bromine! Suspensions containing high solids percentages may clog or
even damage the dosing system.
General:
The safety guidelines that are applicable to the handling of chemicals have to be observed under all
circumstances. This applies in particular to inflammable and/or etching liquids.
