1 Introduction

1.1 Description

The Thin-Layer cell is used for amperometric detection with the Ampero­metric Detector. The Thin-Layer cell especially qualifies for applications
with double detector mode, e. g. if an amperometric detection is followed
by another detection technique.

In the Thin-Layer cell, the sample flows in a thin layer between the auxili­ary electrode and the working electrode and is analyzed with amperomet­ric methods.

1.2 About the documentation

Caution

1 Introduction

Please read through this documentation carefully before putting the
measuring cell into operation. The documentation contains information
and warnings which the user must follow in order to ensure safe opera­tion of the instrument.

1.2.1 Content and scope

Content of this manual

This manual describes:

￭ The insertion of the working electrode in the Thin-Layer cell.
￭ The insertion of the reference electrode in the Thin-Layer cell.
￭ The connection of the capillaries and the electrode cables.
￭ All maintenance work that can be carried out by the user.
￭ The technical specifications of the Thin-Layer cell.
￭ The supplied and the optional accessories.

Further information

Detailed information concerning the insertion of the measuring cell into
the detector can be found in the manuals for the amperometric detector.

Information on the utilization, care and maintenance of the working elec­trodes and reference electrodes can be found in the leaflets which are
enclosed with the electrodes.
