Short summary
Plants emit small amounts of methane and large amounts of volatile organic compounds (VOCs). Measurements of plant methane emissions therefore require analysers that can provide accurate measurements of CH4 concentrations in the presence of changing amounts of VOCs. We therefore quantified to which degree various VOCs bias methane concentration measurements on different analysers. Our results show that some analysers are more sensitive to the presence of VOCs than others.
