Ferrules that are prepared improperly cause leaks and contamination. To avoid
problems, place graphitized Vespel ferrules in a petri dish and bake in the GC
oven at 250 to 300°C for 30 minutes before use to remove organic compounds
absorbed by the graphite. Leave a petri dish of assorted ferrules in the GC oven
to ensure a clean supply.
