pegasus4dFor theory of operation, refer to the GCxGC Spec Sheet (209-184-001). For analytical parameters for the Pegasus BT, refer to the Pegasus BT Spec Sheet (209-251-001).The 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 4D
