7820A GC System

The 7820A Gas Chromatograph system performs great day-to-day analysis. The system provides reliable capabilities for a wide range of application areas, meeting regulatory and SOP needs for small-to medium-sized labs.

Runs with full electronic pneumatic control (EPC) from inlet to detector for good retention time and area count performance. Electronic pneumatic regulation (EPR) offers manual operation simplicity with high precision digital display of pressure/flow. Superior ease-of-use over traditional systems.
