Injector operates by switching the carrier gas flow within the
injection port between Split / Splitless mode of operation. Splitless
mode has a low flow rate of carrier gas within the Injection port
which is insufficient to support the sample vial allowing it to
fall into the injection port for sample collection. Split mode
has a high flow rate of carrier gas which can expels the sample
vial up and out of the injection port.
Low flow rate / Equal to Column flow rate. Used to sweep volatiles
into the capillary column.
High flow rate / Equal to Total Injection Port flow rate. Used
to expel and or keep the sample vial out of the injection port.
