7800 Series GC

The 7890B Gas Chromatograph (GC) System is a widely used GC system, featuring temperature controls, precise injection systems, and high performance Electronic Pneumatic Control (EPC) modules for retention time and area count repeatability. Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column.
