Agilent provides a Vapor Volume Calculator to help you
determine if a liner is suitable for a method. To use the
calculator install the Agilent Instrument utility provided with
the GC. The calculator is also provided with the Agilent
Instrument Utilities software.
Mode The current operating mode—split
Temperature Actual and setpoint inlet temperatures
There is no setpoint for the Pressure parameter in EPR (electronic
pneumatics regulation) equipped GCs with an S/SL inlet.
Pressure Actual and setpoint inlet pressure
Split ratio The ratio of split vent flow to column flow. Column
flow is set at the Column parameter list. This line appears only
if your columns in the flow path are defined.
Split flow Flow, in mL/min, from the split vent. This line
appears only if your columns in the flow path are defined.
Total flow This is the total flow into the inlet, which is the sum
of the split vent flow, column flow, and septum purge flow. When you
change the total flow, the split ratio and split vent flow change while
the column flow and pressure remain the same.
