    experiment_summary: 'Neutral seed was injected with an initial seed surface area of 810 um2/cm3, followed by a Cl2 injection out of a gas cylinder, and the isoprene injection using a heated glass bulb. Temperature was kept at 25C for the whole duration of the experiment, while RH was kept at less than 10%.'

    experiment_set_description: 'Environmental chamber experiments were carried out under low-NOx conditions with isoprene and chlorine as primary VOC and oxidant sources. Secondary organic aerosol yields were calculated upon complete isoprene consumption. Formation of particulate organochloride was tracked using an ACSM. A high-resolution time-of-flight chemical ionization mass spectrometer was used to determine the molecular composition of gas-phase species using iodide?water and hydronium?water cluster ionization.'
