Peak picking and migration time alignment. (a) Visualization of the position of peaks picked from cation datasets acquired by CE-TOFMS. The data originates from a previous analysis of mouse liver extracts after treatment with acetaminophen [13]. (b) The peak sets were aligned to the peak set from Sample 1 using the alignment procedure described in the main text. The function derived by Reijenga et al. [14] for the normalization of migration times in CE was used as the time shift function.
