Sep 5, 2022 · Based on scent-release methods from pheromone research, we describe a simple and cheap method for scent manipulation using silicone rubber (i.e. a silicone septum). Volatile compounds are applied to the septum by soaking the septa for 1 h in a solvent/volatile solution.
Septa can be made from a range of materials including PTFE, silicone, red rubber, luoroelastomers, and butyl to name. few. The materials are layered together in one of three options: Choose a material that is as inert as possible to your sample analyte and makeup solvents.
Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.
