When the sequence starts, the autosampler performs the rinse steps with solvent and then with the sample, after the 6 pumps of the sample the syringe is left inside the sample. The parameters of the GC were monitored to start the sequence and are as programmed. Other Troubleshooting steps were made, but we have not achieved satisfactory results. Among the steps made are: Restart the entire system, reset the autosampler, new method was generated from default, new sequence was generated from default. By pressing the STATUS key on the GC panel theres a message indicating: "External device not ready". Our system is a GC/MS 7890B/5977A with a 7693 A/s.
