Overall, this improved performance of the worker flames generally arose from both an increase in analyte signal and a decrease in baseline noise. The former is likely due to greater chemiluminescence being generated in this battery of flames, possibly from more efficient excitation of the emitting species. Conversely,noise decreased in each case except for S2* emission, which oddly showed little change between flame modes. This indicates a possible difference between the background emission spectra of the worker flames and the analytical flame, but needs further examination to establish. Further, the gas flows through the central channel provide a peak residence time in the space between the worker and analytical flame of only about 10 ms (and 19 ms through the entire detector). Thus, peak dispersion along the channel path cannot account for the difference noted between these flame monitoring modes either. Therefore, the preliminary data here demonstrate that improved response characteristics are attainable in this novel multiple flame monitoring mode of the SS mFPD. Thus, its further development could be potentially beneficial
