![]() ![]() Modern computer systems are inexpensive, powerful and allow analysis techniques that could not have been applied in the past. Software assists handling large amounts of data generated by automated and fast operating analytical instruments. Especially in the area of gas chromatography/mass spectrometry, automatic samplers enable high throughput analyses. Software has become an integral part of analysis techniques. ![]() OpenChrom is available free of charge at. They can be published using open source as well as proprietary licenses. ![]() There are no license constraints regarding extensions. OpenChrom is released under the Eclipse Public License 1.0 (EPL). The software is independent of the operating system, due to the fact that the Rich Client Platform is written in Java. 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. Extended operations like do, undo and redo are supported.Ĭonclusions: OpenChrom is a software application to edit and analyze mass spectrometric chromatographic data. 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. Results: 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. ![]() ( 2017).OpenChrom: a cross-platform open source software for the mass spectrometry analysis of chromatographic dataīackground: Today, data evaluation has become a bottleneck in chromatographic science. The results clearly show a rapid increase in the 14C concentration in tree rings around 660 BC similar to this observed in Park et al. Single-year samples of dendrochronologically dated tree rings of deciduous oak ( Quercus robur) from Grabie, a village near Krakow (SE Poland), spanning the years 670–652 BC, were collected and their 14C content was measured using an AMS technique. A similar increase was observed in 660 BC, with a peak height of about 10‰ (Park et al. 2012) and about 11.3‰ in the period AD 993–994 (Miyake et al. The increase in the 14C content was about 12‰ in the period AD 774–775 (Miyake et al. In both analyzed periods, the sudden increase was observed almost in a single year. ( 2012, 2013, 2014) described a sudden increase of radiocarbon ( 14C) concentration in annual tree rings of Japanese cedar ( Cryptomeria japonica) and Hinoki cypress ( Chamaecyparis obtusa) between AD 774 and 775 and between AD 993 and 994. ![]()
