1 Introduction
The 859 Titrotherm is a Metrohm titrator for thermometric titration. Thermometric titration can be utilized where potentiometric indication is either
not possible or possible only to a limited extent.
For the theory and application possibilities of thermometric titration, we
recommend the monograph: Thomas Smith, Practical thermometric
titrimetry, Metrohm AG, 2006 (Order No. 8.036.5003).
1.1 The 859 Titrotherm in the Titrando system
The 859 Titrotherm is a component of the modular Titrando system. Operation is carried out with a computer containing the software tiamo™
(starting with Version 2.2).
A Titrando system can contain numerous, various kinds of instruments.
The following figure provides an overview of the peripheral devices you
can connect to the 859 Titrotherm.

1.2 Instrument description
The 859 Titrotherm has the following characteristics:
￭ Operation
Operation is carried out using the high-performance PC software
tiamo™, Version 2.2 or higher.
￭ MSB connectors
Four MSB connectors (Metrohm Serial Bus) to control dosing devices
(Dosimat with exchange unit or Dosino with dosing unit), stirrer or
titration stand and Remote Boxes.
￭ USB connectors
Two USB connectors, through which devices such as printers, PC keyboards, barcode readers or additional control devices (USB Sample Processor, Titrando, Dosing Interface, etc.) can be connected.
￭ Measuring interface
Measuring interface with two connectors for two temperature sensors
(Thermoprobes).
1 Introduction
1.2.1 Titration modes, dosing commands and other commands
￭ TET
Thermometric endpoint titration. The reagent addition takes place continuously at a constant dosing rate.
￭ Dosing commands
The following commands for dosing can be selected:
– ADD (adding a predefined volume)
– PREP (rinsing the cylinder and tubings of an exchange or dosing
unit)
– EMPTY (for emptying cylinder and tubings)
– LQH (for executing complex dosing tasks)
￭ Other commands
– STIR (stirrer control)
– SCAN (scanning remote signals)
– CTRL (setting remote signals)
1.2.2 Intended use
The 859 Titrotherm is designed for usage as a titrator in analytical laboratories. Its main area of application is the determination of ions in aqueous
and nonaqueous media. The 859 Titrotherm uses the method of thermometric titration.
859 Titrotherm
This instrument is suitable for processing chemicals and flammable samples. The usage of the 859 Titrotherm therefore requires that the user has
basic knowledge and experience in the handling of toxic and caustic sub-
