Maintenance of the Injection Port
Replacing the Injection Port Septum
A worn out septum causes leakage, which will result in poor reproducibility and an
unstable baseline. When an injection is made, the baseline will suddenly drop below
zero as the needle is pushed against the septum. This will also occur if the septum is
improperly seated in the injection port.
A silicone septum with a Teflon face (MX380320) is recommended for use
with
Explorer. This type of septum will last for about 10 injections depending
on the syringe needle.

1. Move the instrument to an area where the ambient air contains no VOCs.
2. Unscrew the black septum retainer.
3. Use a syringe needle to withdraw the old septum.
