These septa often emit specific volatile organic compounds (VOCs) confounding the measurement results of breath samples. In the current paper, 14 different brands of magnetic caps with silicone–polytetrafluoroethylene (PTFE), butyl–PTFE, or butyl rubber septa were tested. The total emission of septa over a 4 h period was also evaluated.
