GC×GC-TOFMS LECO Pegasus 4D

Obrázek GC×GC-TOFMS LECO Pegasus 4D

Two dimensional capillary GC system, combined with the ultra-fast TOF-MS, changed our possibilities in analyses of complex samples of volatile compounds. No longer limited to two analytical dimensions, the Pegasus 4D GC×GC-TOFMS system (LECO, St. Joseph, Michigan, USA) provides us with four dimensions of analytical resolution for significantly more complete complex sample analysis. With Pegasus we are able to detect hundreds-to-thousands more volatile organic compounds than with previously used conventional one dimensional GC-MS. Separations, which previously resulted in dozens or hundreds of peaks, now yield thousands of individual components from complex mixtures. Other unique processing capabilities (such as sample comparisons) allow for automated mining of complex GC×GC data to extract previously unidentifiable similarities and differences.
