A series of articles describes it: Peak Integration Part 1, Peak Integration Part 2, Peak Integration Part 3. The major tool of the chromatographic software is peaks " integration". Analyzing a chromatogram helps identify and quantify the substances present in the mixture being analyzed. The height, width, and area of the peaks in a chromatogram provide information about the amount and purity of the components in the sample. In a chromatogram, each component of the mixture appears as a peak or band at a specific retention time, which is related to its characteristics, such as molecular weight, polarity, and affinity for the stationary phase. A chromatogram is a graphical representation of the results obtained from the chromatographic system. The data station is connected to the entire instrument, especially the detectors, allowing real-time monitoring of the runs, especially the obtained chromatograms. This is a dedicated software connected to an hardware interface within the chromatographic system, which serves as a central hub for collecting, analyzing, and managing the data generated during the chromatographic analysis. It is located in the data station of the modern liquid, gas or supercritical fluid chromatographic systems. Chromatography software is called also Chromatography Data System).
