PUBLICATION: Hidenori Takahashi, Yuji Shimabukuro, Daiki Asakawa, Shosei Yamauchi, Sadanori Sekiya, Shinichi Iwamoto, Motoi Wada, Koichi Tanaka, "Structural Analysis of Phospholipid Using Hydrogen Abstraction Dissociation and Oxygen Attachment Dissociation in Tandem Mass Spectrometry", Anal. Chem., 90 (12), 7230-7238 (2018). DOI:10.1021/acs.analchem.8b00322.
COMMENT: FRAGMENTATION_MODE is RID that is "Radical Induced Dissociation"; MALDI generates [M+H]+ ion, which is dissociated by the reaction with 3O (triplet O) generated by O2 microwave discharge.
COMMENT: The instrument consists of QIT-TOF where Q selects [M+H]+ ion, IT is an ion trap chamber for the reaction of RID, and TOF analyzes the product ions.
COMMENT: This mass spectral data and fragment ions produced are shown in Figure S6_2 of the publication.
COMMENT: Relative intensity of the peaks m/z 180-199 is magnified by x5, those of the peaks m/z 200-507 by 100.
COMMENT: The sample was injected by direct infusion of methanol solution.
COMMENT: This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 19HP8024 to the Mass Spectrometry Society of Japan.
COMMENT: The lipid standard was purchased from Avanti Polar Lipids (Alabaster, AL).
