Scheme representing the fragmentation pattern for m/z 1413.5 precursor ion ([M + 2Na]2+) and m/z 1682.8 intermediate ion of permethylated Hex11HexNAc2 isolated from the LLO of P. tricornutum. Cleavages of the glycosylic bond and cross ring cleavages are represented by dotted lines. The fragment ions are labelled according to the nomenclature of Domon and Costello [41]
