Tightening the PTV Septumless Head Using the Leak
Test Procedure
If you are using a PTV inlet with a septumless head, you can use the leak test
procedure described in “Carrier Gas Flow Path” on page 105 or “Carrier Gas
Flow Path” on page 110 to help you properly tighten the septumless head onto
the needle. As you tighten the fitting on the needle, monitor the flow rate on the
GC front display. When the flow rate indicates there is no leak, the connection
is tight enough.
