2.1 Starting/closing the program 2 Fundamentals of the operation 2.1 Starting/closing the program 2.1.1 Start the «IC Net» program Start the program Double-click this icon or the ICNet.exe file to start the «IC Net 2.1» program. The IC Net login window appears: Enter your password and click on . After software installation, the program can be started without entering a Password. For the definition of users, see section 3.2. 2.1.
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).
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 (for details, see section 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 (*.
2 Fundamentals of the operation 2.3 Overview of program windows «IC Net 2.1» consists of different windows whose functionality is linked together. The different windows are: 2.4 IC NET Main program window with menus for file administration, printing, method modification, options, login and user rights, window handling. CHROMATOGRAM Chromatogram window for graphic plot of running or recorded chromatograms. SYSTEM System window for control of interfaces and devices.
2.5 Icons of the main window 2.5 Icons of the main window The following icons are displayed in the IC NET main window: Open chromatogram Save chromatogram Open last batch reprocessing file Make report Print preview Send chromatograms to Autodatabase Print chromatogram Passport Method setup Integration Components Cascade all opened chromatogram windows Vertical tiling of open chromatogram windows Horizontal tiling of open chromatogram windows Appearance Enable/disable peak editor mode.
2 Fundamentals of the operation 2.6 Overview of file types The following file types are produced by the «IC Net» software: 12 *.adb Autodatabase file Contains chromatogram and method data of all determinations. *.bar Batch reprocessing file (binary file) Contains batch reprocessing data. The *.bar file is stored automatically in the Data folder. *.cal Calibration file (binary file) Contains calibration data, which can be exported with IC Net / Method / Calibration / Export calibration. The *.
2.7 Context-sensitive menus 2.7 *.rtt Report file (ASCII file) Contains a report template. The *.rtt file is stored in the program folder. *.smt System file (ASCII file) Contains the system settings. The *.smt file is stored automatically in the Systems folder. *.dev Device file (ASCII file) Contains drivers for devices. The *.dev file is stored in the Devices folder.
2 Fundamentals of the operation Shifts a chromatogram on 1/10 part of a screen downwards. [ Shift ] + [ up ] Increases a distance between channels of a chromatogram. [ Shift ] + [ down ] Reduces a distance between channels of a chromatogram. [ 0 (Zero) ] Adjusts a zero on the last point of a chromatogram (running chromatogram) or its lowest level (finished run). Only part of the chromatogram is on screen: [ Ctrl ] + [ right ] Moves one window right (without change of scale on X and Y axes).

If the signal-to-noise ratio of the chromatogram is high enough (e.g. 100:1 or higher), the integration algorithm is not too sensitive to changes in integration parameters. On the contrary, if the baseline noise is high, careful tuning of these parameters may be needed. Number of peaks Number of peaks detected (read-only).

Entry range: 0.1} }100 Threshold for peak recognition.
7 Methods 7.4.3 This function sets up reasonable integration parameters in the following way: x Slope is set to a reasonable value. x Asymmetry is set to a reasonable value. x Width and Broadening are calculated by fitting a straight line through the measured peak halfwidth values vs. retention time. Width is determined as the y value of this line at the Delay time, Broadening is calculated as the y value at the end of the chromatogram divided by the y value at the Delay time.

7.5 Calibration and quantification 7.5 Calibration and quantification 7.5.1 General information The aim of any chromatographic analysis is to answer the question "What components are present in the sample and what are their concentrations?". Two procedures are used to achieve this goal: the first step is called calibration, the second step includes quantification.
7 Methods 7.5.2 Notations R Stands for response value, either area or height, depending on setting selected in the Calibration graphs window. V Sample Volume injected. D Dilution coefficient, shows number of times to which the initial solution is dissolved before injection. V' = V / D Adjusted volume of injected sample. A correction is made for the dilution coefficient. C Concentration of the component in the initial solution (before dilution).
7.5 Calibration and quantification 7.5.3 External standard calibration External standard calibration (absolute calibration) is a key way of calibration. Basically this procedure calculates the dependence of injected component's quantity versus area (or height) of the corresponding peak. This dependence is showed as a calibration plot with injected quantity along the Y axis and peak area (or height) along the X axis.
7 Methods 152 Number Row number (read-only). Peak Number of the peak in the chromatogram that corresponds to the given component. If this field contains a 0, the peak number must be entered manually.
