    experiment_summary: '1,2-DHI and CH3ONO were injected, AS solution was atomized, and lights were turned on to initiate photooxidation. Only 33% of lights were on for the first 7 minutes; all lights were turned on for the rest of photooxidation. A DNPH cartridge was collected after photooxidation to analyze for carbonyl content.'
