Item Description
Stabilization Time 0.00 - 10.00 min
Shows the 3900 GC column oven stabilization time in
minutes. The stabilization time counts down from the
programmed method value and then displays 0.00
minutes when the stabilization period is over.
Injector EFC Status Display
Injector EFC Status:
Item Description
Flow Ready Yes or No.
The Type 1 Injector EFC component is Ready (Yes) if the
setpoints have been achieved and stabilized. The Type 1
Injector EFC component is Not Ready (No) if readiness to
start a run has not been achieved or if, during a run, the
EFC becomes not ready or goes “out of tolerance”. Some
reasons the GC may go Not Ready during a run are: the
temperature program is too aggressive, the oven door is
opened, the coolant runs out, the power line voltage drops,
etc.
Pressure Ready Yes or No.
The Type 1 Injector EFC component is Ready (Yes) if the
setpoints have been achieved and stabilized. The Type 1
Injector EFC component is Not Ready (No) if readiness to
start a run has not been achieved or if, during a run, the
EFC becomes not ready or goes “out of tolerance”. Some
reasons the GC may go Not Ready during a run are: the
temperature program is too aggressive, the oven door is
opened, the coolant runs out, the power line voltage drops,
etc.
Type 1 Pressure
Setpoint
0.1 - 100 psi
Displays the programmed column head pressure setting in
the active method.
Actual Pressure 0.1 - 100 psi
Displays the actual column head pressure at the 3900 GC.
Column Flow Displays, in ml/min, the column flow rate calculated from
the column head pressure, column temperature, and
column parameters (carrier gas, column length, and
internal diameter).
