Table 1 Comparison of collision cross section (CCS) and minimum resolution (R) that is required to resolve the peaks of selected isomeric ions in an ion mobility spectrum (R = CCS/ΔCCS). The CCS calculations were carried out by using the ion mobility spectrometry suite (IMoS) via the parallelized user interface (ParsIMoS) (Kune 2018)
