1.1 Purpose of program

1 Introduction

1.1 Purpose of program
«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).

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-

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 Bischoff interfaces 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).

Some of the menu functions of the program windows are also ac­cessible by clicking on the desired window or item and pressing the right mouse button. The pop up windows have different contents and functions depending on the selected active window or item type.

2.8 Keyboard and mouse functions

The mouse can be used to carry out the normal program operat- ing functions such as the selection of menu items and fields. It can additionally be used for magnifying a section of a chroma­togram (zooming). To zoom a portion of the plot it is necessary to place the mouse cursor to the upper left corner of the square to zoom, press the left mouse button and drag the cursor to the lower right corner of the rectangle. After releasing of the left mouse button the selected region will be zoomed full-screen. If the cursor is active in the peak editor mode then it can be moved by pressing down the right-hand mouse key.
The keyboard can also be used to scale a chromatogram in the window, as described below.

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 732/733 Instructions for Use. Examples for interconnections with the 733 IC Separation Center, the 732 IC Detector and the 762 IC Interface can be found in the 762 Instructions for Use.
