Mass spectrometry studies of lycodine‐type Lycopodium alkaloids: sauroxine and N‐demethylsauroxine

“…For the analysis of (CID) product ions, the precursor was selected using a MS/MS standard function, with 0.5–1.0 Da peak width for the precursor ion, and dynamically programmed scans. The supplementary voltage was in the range 0.5–1.0 V, as described previously …”
