1 Introduction

1.1 Description of the IC equipment: Inline-Ultrafiltra­tion

The IC equipment: Inline-Ultrafiltration (6.5330.110) contains all accesso­ries required for Inline Ultrafiltration of difficult samples directly before
injection.

The main component of the IC equipment: Inline-Ultrafiltration is the
high-performance ultrafiltration cell. This cell is suitable for the filtration of
samples that pose particular requirements with regard to filtration effec­tiveness and sample throughput.

The two channels of a peristaltic pump are required for pumping the sam­ple and the filtrate.

1.2 About the documentation

This manual describes the correct assembly and maintenance of the IC
equipment: Inline-Ultrafiltration, the installation of the capillary connec­tions to and from the ultrafiltration cell and how to mount the holder on
both the Sample Processor and the IC instrument.

The installation of the peristaltic pump is not described in this manual. This
description can be found in the respective manuals for the ion chromato­graph or the Sample Processor.

CAUTION

Please read through this documentation carefully before putting the IC
equipment: Inline-Ultrafiltration into operation. The documentation
contains information and warnings which the user must follow in order
to ensure safe operation of the IC equipment: Inline-Ultrafiltration.
