Table S8b t-test Comparisons between Fuels at the 75% Load Point Table S9 (a) t-test Comparisons between Instruments at the 25% Load Point Table S9 (b) t-test Comparisons between Instruments at the 75% Load Point BC mass concentration presented in mass per volume units for the 25% load points The graphs in this section show the lower concentration levels from Figure 4, which represent the 25% load points, in greater detail. Figure S4: Various Instrument Responses with respect to PAS Mass Concentration at 25% load BC mass concentrations for the RMB-30 and RMG-380 Fuels Normalized by the DMA Fuels Some additional comparisons were also done by normalizing the results for the different instruments for the RMB-30 and RMG-380 fuels by the corresponding results from the DMA fuel. These results are shown in Figure S5. For the normalized RMB-30 fuel results, there were no significant changes in slope for most instruments relative to the PAS, with the exception of the TOA-ES and the Aethalometer. TOA-ES: A decrease in the slope was observed for the TOA-ES. As mentioned in the BC instrument comparison section, it was observed that the split points for both the DMA and the RMG-380 fuels were early, suggesting either a catalytic effect due to the presence of metal
