pegasus 4dThe Pegasus BT 4D offers enhanced sensitivity by coupling our benchtop Pegasus BT with a hh performance GCxGC modulation system. This combination gives the Pegasus BT 4DThe Pegasus 4D GCxGC-TOFMS is a Comprehensive Two-Dimensional Gas Chromatography with Time-of-Flht Mass Spectrometer. GCxGC, combined with the Pegasus HT TOFMS, changes the dynamic when analyzing complex
