1 Introduction

1.1 The 846 Dosing Interface in the Titrando system

The 846 Dosing Interface is a component of the modular Titrando system.

It is operated either by means of a Touch Control with a touch-sensitive

screen or through a computer with a corresponding software, e.g.

tiamo™ or MagIC Net™.

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 846 Dosing Interface.

1.2 Instrument description ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

2￭￭￭￭￭￭￭￭ 846 Dosing Interface

When a Touch Control is used as the operating unit, up to three control

devices (Titrandos, Dosing Interfaces, USB Sample Processors, etc.) can be

controlled via USB connection. If a PC software (tiamo™ or

MagIC Net™) is used, then there is no limit to the number of control

devices that can be used to extend the system.

Updating the device software is described in the manual for the Touch

Control or in the online help for the control software.

1.2 Instrument description

The 846 Dosing Interface is a very versatile instrument. It was designed

exclusively for operational and laboratory use and covers a wide spectrum

of applications in this context.

Because it is equipped with high-performance USB interfaces, it can be fit-

ted seamlessly in a Titrando system from Metrohm. The versatile commu-

nications options of the Titrando system (Remote Box, LIMS link, etc.) can

thus all be used. Thanks to these capabilities, a 846 Dosing Interface is

predestined for all imaginable dosing and Liquid Handling tasks in modern

laboratory operations, particularly within highly integrated laboratory data

systems.

The user interface of the Touch Control or of the tiamo™ or

MagIC Net™ software ensures convenient operation and programming

of the 846 Dosing Interface. The integration in the Titrando system also

ensures 100%conformance with the guidelines of the FDA (Food and

Drug Administration) for the entire instrument system, in particular with

Guideline 21 CFR, Part 11, Electronic records and signatures.

The 846 Dosing Interface has the following characteristics:

￭Operation

Operation is carried out by means of a touch-sensitive Touch Control or

with a high-performance PC software, e.g. tiamo™.

￭Dosing

Dosinos and Dosimats can be used for dosing. These enable the dosing

of auxiliary solutions or the carrying out of complex Liquid Handling

tasks.

￭MSB connectors

Four MSB connectors (Metrohm Serial Bus) are available for controlling

Dosinos, stirrers and Remote Boxes.

￭USB connectors

Two USB connectors, through which devices such as printers, PC key-

boards, barcode readers or additional control devices (Titrando, USB

Sample Processor, Dosing Interface, etc.) can be connected.
