² (Demo mode: |
After reaching the target gas pressure, the GC waits the time specified under PressureEquilibration |
Notes:
² When connecting, Chromeleon reads the value from the instrument and accepts it as default.
³ When a temperature has been defined, the mode is automatically set to RampedTemperature. It is not possible to set the temperature in TrackOven mode (the inlet temperature is automatically set to the oven temperature).
