![]() It offers a customizable graphical user interface. ![]() It is extensible in many different ways, depending on the demands of the users or the analytical procedures and algorithms. OpenChrom is a software application to edit and analyze mass spectrometric chromatographic data. Extended operations like do, undo and redo are supported. Additionally, filters can be applied on the chromatographic data to enhance its quality, for example to remove background and noise. The approach can be extended in its functionality such as facilities to detect baselines, to detect, integrate and identify peaks and to compare mass spectra, as well as the ability to internationalize the application. This work describes a native approach to handle chromatographic data files. These applications provide functionalities to import and analyze several data formats but have shortcomings in terms of the transparency of the implemented analytical algorithms and/or are restricted to a specific computer platform. To challenge this situation a number of either commercial or non-profit software applications have been developed. Since nearly every GC/MS instrument vendor offers its own data format and software tools, the consequences are problems with data exchange and a lack of comparability between the analytical results. Analytical instruments equipped with automated samplers yield large amounts of measurement data, which needs to be verified and analyzed. Today, data evaluation has become a bottleneck in chromatographic science.
