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: What is "Radical Induced Dissociation" (RID)? Microwave discharge of H2O generates OH*, H* and 3O (triplet O) radicals. These radicals react to dissociate the stable [M+H]+ ion.
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 4(A) of the publication. Fragment ions produced are annotated in Scheme 2. MS data of the substance is MSJ00178; Figure 1(A) Inset in the publication.
COMMENT: Relative intensity of the peaks from m/z 300 to 499 is magnified 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).
