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: This is an experiment to compare with MSJ00179 that uses Hydrogen Abstraction Dissociation (HAD) instead of CID for the dissociation of [M+H]+.
COMMENT: This mass spectral data is shown in Figure S3 of the publication.
COMMENT: The instrument consists of QIT-TOF where Q selects [M+H]+ ion, IT is an ion trap chamber for the reaction of HAD, and TOF analyzes the product ions.
COMMENT: MS data of the substance is MSJ00178; Figure 1(A) Inset in the publication.
COMMENT: The sample was injected by direct infusion.
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).
