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 4).
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 de­vice. 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
6
IC Net 2.0
Interface
Method
2.2 Glossary
baselines. The integration algorithm included in the program is influenced 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).
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).
A method contains all information necessary for data acquisi- tion, 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 (*.smt) in the Systems direc­tory (for details, see section 4).
Workplace
The workplace contains all interfaces and devices connected directly to the PC COM ports and all systems connected to the interfaces. The icons of all these active interfaces, devices and systems are shown on the toolbar. They can also be displayed in the Workplace window opened by selecting the Options / Devices
setup menu item (for details, see section 3.3).
