Agilent 7820A GC System

The Agilent 7820A GC system performs great for day-to-day analysis and meeting regulatory and SOPs for small-to medium-sized labs.

The Agilent 7820A GC 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. The Agilent 7820A gas chromatograph, inheriting Agilent’s legendary expertise in GC and proven quality as industry leader, generates reliable results with minimized complexity for customers’ routine analyses, run after run, day after day. The simplified GC front panel keys and display provide sequence information, instrument conditions, and run status. Full electronic pneumatics control (EPC), available for all inlets and detectors, automates control of gas pressures/flows to predefined set points, and allows pressure and flow programming. Electronic pneumatics regulation (EPR) is available for select inlets and detectors. EPR provides a digital measurement and display of gas pressure/flow and allows
the user to manually adjust these gas pressures/flows, electronically, using the 7820A software keypad on the user’s PC, avoiding use of mechanical regulators. This provides constant pressure operation for the Split/Splitless inlet, and constant flow operation for the Packed Column inlet and the detectors with EPR. If desired, EPR actual pressure and flow can be saved as additional signals with any OpenLAB CDS software to record its operation for each GC run. EPC and EPR are compensated for barometric pressure and ambient temperature changes, which results in more stable retention times and detector baselines. Configurable with a range of optional automated sample injectors and samplers.
