Figure 1:
Three generations of SID designs developed in the Wysocki laboratory. ‘Gen 1’ devices have SID lengths >3 cm and consist of 10–12 SID electrodes. ‘Gen 2’ devices consist of tilted surfaces with fewer electrodes and occupy approximately half the volume as their ‘Gen 1’ counterparts. ‘Gen 3’ devices, reported here, occupy approximately 3 mm along the ion path and consist of only three lenses, surface, deflector, and extractor. SRIG = stacked ring ion guide. SID = surface-induced dissociation cell. IM = ion mobility.
