The study tested ways to stop nitrogen dioxide from affecting the measurement of dimethylsulfide in the air. Scientists tried different methods by making scrubbers using different materials and chemicals. They found that scrubbers made with specific combinations, like filter paper with iron sulfate, pyrogallic acid, and sulfuric acid, worked best. Another effective scrubber was made with paper coated with triethanolamine. Results from lab tests and field experiments showed these scrubbers can successfully prevent oxidation during sampling, making them good for accurately measuring dimethylsulfide levels in the atmosphere.
