GCxGC data analysis of msFineAnalysis AI Ver. 3 ① Diesel fuel
Introduction
The qualitative analysis software msFineAnalysis AI enables automatic structure analysis of unknown compounds not registered in libraries through EI/SI integrated analysis and AI structure analysis. Ver. 3 newly supports comprehensive 2D GC (GCxGC) data analysis. Figure 1 shows a schematic diagram of GCxGC-MS and the 2D chromatogram. In GCxGC, two columns with different polarities are connected via a modulator. The sample separated by the first column is cryogenically trapped by the modulator and then thermally introduced into the second column at a few-second interval. For example, using a non-polar column in the first dimension for separation by boiling point and a polar column in the second dimension for separation by polarity significantly enhances compound separation capability. This technique is effective for petroleum, chemical, food, fragrance, and environmental analysis, which have many components and are difficult to analyze using a single GC-MS. This MSTips introduces the features and capabilities of the system using diesel fuel analysis as a basic application example.
