(a) (left panel) ATD of Man1 after one IMS separation cycle; (right panel) ATDs of the diacetyl-chitobiose fragments produced by CID from peak 1 (blue) and peak 2 (red) of Man1, after three IMS separation cycles. (b) (left panel) ATD of Man3 after one IMS separation cycle and (right panel) ATDs of the diacetyl-chitobiose fragments produced from peak 1 (blue) and peak 2 (red) of Man3, after three IMS separation cycles. (c) (left panel) ATD of Man5 after one IMS separation cycle and (right panel) ATDs of the diacetyl-chitobiose fragments produced from peak 1 (blue) and peak 2 (red) of Man5, after three IMS separation cycles. The differences in the absolute drift time of diacetyl-chitobiose obtained when fragmenting different molecules is due to different conditions needed for the optimal separation of the parent ions.
