Tips for Handling Septa
All septa, regardless of composition, punctura-
bility, or resistance to thermal degradation will
fail if they are mishandled. Overtightening a
septum nut invariably will reduce septum life-
time by increasing coring/splitting. All septa
contain volatile materials (e.g., phthalates) that
are released when the septum is heated (sep-
tum bleed). Because most GCs are equipped
with a septum purge, septum bleed generally
will disappear within 30 minutes after installing
a new septum and exposing it to normal injec-
tor temperatures. All Restek septa are precondi-
tioned and are ready to use without delay.
