Short summary

Hydrogen (H₂) and carbon monoxide (CO) are atmospheric trace gases cycled via microbial metabolisms. We observed strong H₂ and CO contamination from rubber septa used to seal common gas sample storage vials. Here we propose a simple and inexpensive modification of such vials to allow reliable storage of H₂, CO and methane trace-gas samples for timescales of weeks to months, thus enabling extensive field campaigns to investigate H₂ and CO biogeochemistry in remote areas.
