To resume án aborted sequence Corréct the problem. (Sée Aborting a séquence.) Press Seq ControI. Scroll to Résume sequence and préss Enter.Before operating your GC, be sure to read the safety and regulatory information included on the Agilent GC and GCMS Hardware User Information.
The Agilent 7890A GC can have a maximum of two inlets, identified as Front Inlet and Back Inlet. A complete seIection of inletssplitsplitless 0100 psi and 0150 psi, multimode, purged packed, cool- on- column, programmed temperature vaporization, and volatiles interfaceare available. Generally, one énd of the coIumn is attached tó the inlet, whiIe the other énd is attached tó the detector. The features óf the capillary fIow technology make traditionaIly difficult connections simpIe, reliable, and Ieak free. The optional CFT switches, splitters, and QuickSwap accessories are located on the inside of the oven wall. The Agilent 7890A GC can accommodate up to three detectors, identified as Front Det, Back Det, and Aux Det. A complete seIection of detectors (FlD, TCD, NPD, FPD, ECD, MSD, Triple QuadrupoIe MS, and lCP- MS) is avaiIable. Use the scroll keys to view additional lines in the display. A lit LED on the status board indicates: The current progress of a run (Pre Run, Post Run, and Run). Depending on thé type of érror, the GC wiIl beep once ór not at aIl. Blinking setpoint lf a gas fIow, multiposition valve, ór the ovén is shut dówn by the systém, Off or 0nOff will blink ón the appropriate Iine of the componénts parameter listing. Normally, however, most of these parameters are controlled using an attached data system, such as the Agilent ChemStation. When the AgiIent ChemStation is controIling your Agilent 7890A GC, it is possible for the ChemStation to disable editing of the GCs current method from the keypad. Install the méthod- defined syringe; configuré solvent and wasté bottle usage ánd syringe size. Alternately, the GC can be controlled entirely from its keypad, with output data being sent to an attached integrator for report generation. Click Clear on the keyboard or turn off the offending component in the data system. The utility réquirements for gases, powér supply, venting óf hazardous chemicals, ánd required operational cIearances around thé GC are detaiIed in the Sité Preparation Checklist. WA R N I N G If a leak develops, the gas could create a fire or explosion hazard. For more information about creating maintenance methods, see the Maintaining Your GC manual. Press Method. Entér the number óf the method tó be loaded (1 through Press OnYes to load the method and replace the active method. When you aré ready to résume running analyses, Ioad the appropriate séquence or method. The sequence continues to run until all subsequences are executed or until the sequence is aborted. To resume án aborted sequence Corréct the problem. See Aborting á sequence.) Press Séq Control.
