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: MALDI generates a stable [M+H]+ ion. [M+H]+ reacts with the mixture of OH* and H* radicals, and 3O (triplet O) atom that microwave discharge of H2O generates. The reaction products, consisting of [M+H+H*], [M+H+O]+ and [M+H+OH*]+ ions, are dissociated to give product ions, which are detected as RID product ions.
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 is shown in Figure S5 of the publication. Fragment ions produced are explained in Scheme 2 of the publication. MS data of the substance is MSJ00178; Figure 1(A) Inset in the publication.
COMMENT: Relative Intensity of the peaks is magnified; m/z 180-199 by x5, m/z 200-505 by x100
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).
