Abstract
Most laboratory atmospheric chamber studies examining properties of secondary organic aerosol (SOA) perform such experiments with mixing ratios of volatile organic compounds (VOCs) well-above atmospheric relevance (≳50 ppbv). When performing ozonolysis of biogenic VOCs at mixing ratios of atmospheric relevance (≲10 ppbv), repeatability of replicate experiments is hindered by the limitations of conventional VOC injection techniques. To overcome these limitations, two novel components were embedded in a conventional VOC injection setup. Implementation of these novel components has resulted in improvements in variability between replicate chamber experiments of up to a factor of 7 for all particle metrics
