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.
The two split modes—with or without a pressure
pulse—divide the gas stream entering the inlet between the
column flow and the split vent flow through the solenoid
valve. The ratio of the split vent flow to the column flow is
called the split ratio.
The next figure shows the flows with split and pulsed split
modes.
