1 Introduction
1.1 Description of the IC equipment: Dialysis
The IC equipment: Dialysis (6.5330.100) contains all accessories required
for inline dialysis of matrix-contaminated samples (e.g. emulsions, samples
containing fat and protein, body fluids or waste waters with high pollu-
tion loads) directly before injection.
The main component of the IC equipment: Dialysis is the high-perfor-
mance dialysis cell. The ions travel through the semipermeable membrane,
diffusing out of the flowing sample and into the stationary acceptor solu-
tion, where they are preconcentrated. The ion-preconcentrated acceptor
solution is then subsequently injected directly into the IC system.
To operate the dialysis cell, you need an IC system with a peristaltic pump
and a cell holder as well as a Sample Processor with a peristaltic pump.
1.2 About the documentation
This manual describes the correct assembly and maintenance of the IC
equipment: Dialysis as well as the installation of the capillary connections
to and from the dialysis cell. In addition, it describes how the dialysis
works and provides information on applying and optimizing the dialysis.
The installation of the peristaltic pump is not described in this manual. This
description can be found in the respective manuals for the ion chromato-
graph or the Sample Processor.
CAUTION
Please read through this documentation carefully before putting the IC
equipment: Dialysis into operation. The documentation contains infor-
mation and warnings which the user must follow in order to ensure
safe operation of the IC equipment: Dialysis.
