A summary of the results from each experiment performed in the studies of ion fragility during ion transport. From these results, it was determined that all sodiated species studied were less susceptible to fragmentation that can occur before mass analysis. However, in the analysis of protonated PE (16:0/16:0), a high degree of fragmentation was not observed, as was the case for both PC (16:0/16:0) and SM (d18:1/16:0).
