«IC Net 2.2» is the name of the data acquisition and control
software for PC-controlled ion chromatographic systems consisting of Metrohm and Bischoff instruments. The current version is a
true 32-bit application. It was designed specially to operate under Windows 2000 and Windows XP and uses all its benefits.
The «IC Net 2.2» program can be used to create systems for recording and evaluating chromatograms. Time programs can also
be created in which a large number of instrument functions can
be triggered for each program step. It is also possible to use programmable signals to control external instruments.
The operating software meets all the requirements you could
place today on a modern integration software: single or multipoint calibration, internal or external standard, selectable algorithms for non-linear calibration, various integration modes with integration parameters and integration events, different methods for
peak recognition, peak editor, free scaling, superimposing several chromatograms, use of sample tables and batch reprocessing; a powerful and GLP-conform report generator with output interfaces for monitor, printer and external databases.
The «IC Net 2.2» software can be configured and used in order
to comply with the Electronic Records and Signatures Rule,
known as 21 CFR Part 11, established by the U.S. Food and
Drug Administration (FDA). For this purpose, the program contains password protection, user administration, electronic signatures, audit trail and administration of methods and results in databases. To use the 21 CFR Part 11 features of «IC Net 2.2» the
operating system Windows 2000 or Windows XP with NTFS file
system is required.

2 Fundamentals of the operation
2.2 Glossary
Batch reprocessing
Batch reprocessing is understood to be the subsequent reprocessing of a series of chromatograms which have been loaded in
a batch reprocessing queue. During reprocessing with a selected
method the settings for calibration, integration, passport, appearance and report can be altered at will (for details, see section 10).
Calibration
Calibration is used to describe the method of determining the relationship between the peak height or peak area found for one
component and its concentration in the sample. The result of the
calibration is a calibration function (calibration curve), which
shows the relationship between the amount of sample and the
evaluated quantity.
The determination of the calibration function with reference solutions can be carried out as a one-point or as a multiple-point calibration. The calibration method which is mainly used in ion
chromatography is the external standard calibration (absolute
calibration); calibration with an internal standard (relative calibration) or tabulated calibration are also possible (for details,
see section 7.5).
Chromatogram
A chromatogram is a graphic plot of the elution curve (signal vs.
time) recorded following a chromatographic separation on a
separating column.
Chromatograms are stored as chromatogram files (*.chw) in the
Data directory. As well as the measuring data the chromatogram
files also contain the method parameters and system settings
which have been used for data recording, data processing and
remote control (for details, see section 8).
Determination
In order to carry out a determination a suitable system must be
selected for the separating problem. The result of the determination is a chromatogram, in which the measuring data and results
of the determination are stored (for details, see section 8).
Device
The «IC Net» program supports remote control for Metrohm and
Bischoff instruments. Each instrument within a system is a de-vice. Devices are stored as device files (*.dev) in the Devices directory. All Metrohm devices start with Me*.dev and all Bischoff
devices start with Bi*.dev (for details, see section 6).
8
Integration
Integration is to be understood as being the method for determining the peak area and peak height with the aid of approximate
baselines. The integration algorithm included in the program is in-
IC Net 2.2
2.2 Glossary
fluenced by the integration parameters and the optionally programmable integration events which are defined in the method.
In addition, the integration can be manually corrected later with
the aid of the peak editor (see section 8.4), for details see sec-tion 7.
Interface
The «IC Net» program supports remote control for interfaces
available from Metrohm and Bischoff. Interfaces generally convert
analog signals to digital form, which can be handled by the computer. Interfaces are stored as device files (*.dev) in the Devices directory. All Metrohm interfaces and Metrohm devices start
with Me*.dev; all Bischoffinterfaces and Bischoff devices start
with Bi*.dev (for details, see section 5).
Method
A method contains all information necessary for data acquisition, integration, peak evaluation and quantification. It can
be considered as the chromatogram template, i.e. chromatogram
without raw data. Methods are stored as method files (*.mtw) in
the Methods directory.
Each system is linked to a method. This method is called proc-essing method and is opened automatically at the start of a new
determination (for details, see section 7).
Sample queue
A sample queue is used for the automated processing of series
of samples, particularly in combination with a sample changer (for
details, see section 9).
System
The combination of Metrohm and Bischoff devices connected to
an interface is called a system. The system includes all the settings of the devices, their time program, the data acquisition parameters and the processing method which have been optimized
for the specific separating column and the determination to be
carried out with it. A system is used to start single determinations
or determinations with the help of a sample queue.
Systems are stored as system files (
tory (for details, see section 4).
Workplace
The workplace contains all interfaces and systems connected to
the PC COM. The icons of all these active interfaces and systems
are shown on the toolbar. They can also be displayed in the

The combination of Metrohm and Bischoff devices connected to
an interface is called a system. The system includes all the settings of the devices, their time program, the data acquisition parameters and the processing method which have been optimized
for the specific separating column and the determination to be
carried out with it. A system is used to start single determinations
or determinations with the help of a sample queue. Systems are
stored as system files (*.smt) in the Systems directory.

6.6 733 IC Separation Center
6.6.1 733 IC Separation Center features
The Metrohm 733 IC Separation Center is a thermally and electronically isolated wet part which accommodates injectors, columns, detectors, suppressor module and pulsation dampener
and is controlled by and connected to the 732 IC Detector. The
following versions are available:
• 2.733.0010 IC Separation Center with 1 injector
• 2.733.0120 IC Separation Center with 2 injectors, metal-free
• 2.733.0130 IC Separation Center with 1 injector and 1 sup-
pressor module, metal-free
The 733 IC Separation Center, which is normally operated by the
732 IC Detector, can be fully operated using the «IC Net» program.
The 733 IC Separation Center with one injection valve is normally connected to the 732 IC Detector using the 6.2125.090 cable. For the operation of a 733 IC Separation Center with two independent columns and two injection valves, two individual
732 IC Detectors are needed. Each of this detectors is connected
to the 733 IC Separation Center using a 6.2125.090 cable. For
operation of a two-valve system with «IC Net», two 732 icons and
two 733 icons (one for valve A and one for valve B) have to be installed in the SYSTEM window. To install the 733 IC Separation
Center in a system the 733 IC Separation Center device must be selected, the type of Separation Center is detected automatically.
If the Separation Center is connected to the 762 IC Interface,
one 6.2115.070 cable for every event line is needed. The number
depends on the type of Separation Center, i.e. for the 733.0130 IC
Separation Center three event lines are necessary to control the
valve (fill, inject) and the suppressor (step). In this case the appropriate 733.0XX0 Separation Center device must be selected to
install the 733 IC Separation Center in a system.
For detailed information about the 733 IC Separation Center see
