Comprehensive Two-Dimensional Gas Chromatography with Time-of-Flight Mass Spectrometer Description GCxGC, combined with the Pegasus HT TOFMS, changes the perspective of complex sample analysis. No longer limited to two analytical dimensions, the Pegasus 4D GCxGC-TOFMS system provides you with four dimensions of analytical resolution for significantly more complete complex sample analysis. With LECO GCxGC you are able to detect hundreds-to-thousands more compounds than previously seen using conventional GC. Separations, which previously resulted in dozens or hundreds of peaks, now yield thousands of individual components from complex mixtures. Powerful, easy-to-use Windows-based ChromaTOF® software simplifies component identification—providing you with a significant increase in efficiency and productivity. Other unique processing capabilities (such as sample comparisons) allow for automated mining of complex GCxGC data to extract previously unidentifiable similarities and differences. Features - Integrated control of all GC, modulator, TOFMS, and auto sampler
system components - Comprehensive GCxGC capabilities
- Comprehensive quantitative analysis of target analytes
- Qualitative analysis with Automated Peak Find and True Signal Deconvolution® algorithms
Highlight Two-Dimensional Gas Chromatography Two-dimensional gas chromatography occurs by the repeated re-injection of effluent from one chromatographic column into a second column. The cycle of refocusing and re-injection is matched to the time required for compounds to elute from the second GC column, resulting in a separation of compounds across a plane, rather than just along a line. With the LECO GCxGC system this is accomplished with a dual-stage, quad-jet thermal modulator positioned between the two columns.
