  text: In order to standardize spray flame synthesis (SFS) studies, intensive work
    has been done in recent years on the design of burner types. Thus, in 2019, the
    so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized
    in numerical and experimental studies. Based on this research, a modification
    of the nozzle design was proposed, which has now been considered in the successor
    model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation
    on the particle formation, we operated both burners under identical operating
    conditions to produce maghemite. The final powder comparison showed that SS2 yielded
    considerable higher specific surface areas (associated with smaller primary particle
    sizes), lower polydispersity, and higher phase purity. To obtain further information
    on the size distributions of aggregates and agglomerates generated by SS2, aerosol
    samples were extracted by hole in a tube (HIAT) sampling and characterized by
    scanning mobility particle sizing (SMPS). Samples were extracted along the centerline
    at different heights above the burner (HAB) above the visible flame tip (>7 cm),
    and quenching experiments were performed to extract the aerosol samples at different
    dilution rates. Thereby, it was demonstrated that performing detailed quenching
    experiments is crucial for obtaining representative HIAT-SMPS data. In particular,
    agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were
    not sufficiently diluted. If sufficient dilution was applied, distribution widths
    and mean particle mobility diameters were determined with high accuracy (sample
    standard derivation <5 %). Our data suggested the evolution of primary particle
    sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates
    present above the visible flame were compact in structure (non- fractal). The
    mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7
    cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.
