1 Introduction

1.1 Instrument description

Existing 850 Professional IC instruments can be expanded to include addi-

tional functions by means of extension modules. Every 850 Professional IC

instrument can be supplemented with up to 3 extension modules.

The 872 Extension Module – Liquid handling extends the possibilities

of inline sample preparation and liquid handling. Up to six auxiliary solu-

tions can be provided in the instrument. A mixing vessel that can be

mounted on the instrument allows the mixing of different solutions. The

872 Extension Module – Liquid handling makes guard column reactions

and pH adjustments possible - and much more.

The extension module is operated with MagIC Net software, just like the

IC instrument. When it is connected to an 850 Professional IC instrument,

MagIC Net recognizes the extension module automatically and checks its

functional capability. It controls and monitors the IC instrument as well as

the extension module, evaluates the measured data and administers it in a

database.

The 872 Extension Module – Liquid handling comprises the following

components:

10-port valve

The 10-port valve is utilized for sample preparation and serves as a switch-

over point between different liquids.

Peristaltic pump

The Peristaltic pump is used for pumping sample and auxiliary solutions. It

can rotate in both directions.

Injection valve

In Liquid Handling the injection valve is used for the measurement of pre-

cisely defined smaller volumes. The liquid is measured in the sample loop

and injected into the sample preparation process by means of valve

switchover.

2￭￭￭￭￭￭￭￭ 872 Extension Module – Liquid handling

1.2 Intended use

With the 872 Extension Module – Liquid handling, an 850 Profes-

sional IC instrument can be extended to include a broad range of addi-

tional sample preparation possibilities without having to modify the instru-

ment in between. For example calibration, ion exchange, guard column

reactions or a combination of several of them.

The present instrument is suitable for processing chemicals and flammable

samples. The usage of the 872 Extension Module therefore requires that

the user has basic knowledge and experience in the handling of toxic and

caustic substances. Knowledge with respect to the application of the fire

prevention measures prescribed for laboratories is also mandatory.

1.3 About the documentation

1.3.1 Content and scope

This document describes the 872 Extension Module – Liquid han-

dling, its assembly and connection to the IC instrument, as well as the

installation, operation and maintenance of the individual components.

Technical specifications, troubleshooting and information concerning

scope of delivery and optional accessories makes up the rest of the man-

ual.

This document does not on the other hand describe the functions of the

IC instrument - extension module unit, nor does it describe the capillary

connections that proceed from the extension module. For this purpose,

please refer to the manual for the IC instrument and that for the sample

processor.

Additional information concerning the configuration of MagIC Net can be

found on the online help for MagIC Net.
