In-source CID ramping (InCIDR). (A) The data acquisition scheme of InCIDR. We used 8 scan events in each cycle to examine the intensity change of the covariant ions. (B) The trend of the intensity change as the CID energy level is ramped. The fragment ion ([H2PO4]) and the adduct ion ([M+NaAc-H]-) of Glc6P follow the predicted pattern. (C-D) Example InCIDR results for Glc6P and NAD.
