Chromatography software is called also Chromatography Data System. It is located in the data station of the modern liquid, gas or supercritical fluid chromatographic systems. 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. The data station is connected to the entire instrument in modern systems, especially the detectors, allowing real-time monitoring of the runs, exhibiting them as chromatograms. A chromatogram is a graphical representation of the results obtained from the chromatographic system. 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. The height, width, and area of the peaks in a chromatogram provide information about the amount and purity of the components in the sample. Analyzing a chromatogram helps identify and quantify the substances present in the mixture being analyzed.

Integration & Processing

The major tool of the chromatographic software is peaks "integration". A series of articles describes it: Peak Integration Part 1, Peak Integration Part 2, Peak Integration Part 3. The parameters inside the chromatography software which affect the integration are called the Integration events. Peak integration in any chromatographic software refers to the process of quantifying the areas under the peak's curve in the chromatogram. The area under the peak is proportional to the amount of that particular component in the sample. Here are the basics of peak integration in a chromatographic system: Applications are also available for simulation of chromatography, for example for teaching, demonstration, or for method development &/or optimization.

Software Packages

Many chromatography software packages are provided by manufacturers, and many of them only provide a simple interface to acquire data. They also provide different tools to analyze this data. The following is a list of software and the (unexplained) tools that each provides. Please note that some of them were discontinued with the years.
