METHODS FOR ANALYSIS OF LIPIDS USING MASS SPECTROMETRY |
摘要 |
A method and apparatus for analyzing samples using mass spectrometry are disclosed. The apparatus includes a reaction device configured to dissociate sample ions into fragments by reacting the sample ions with a charged species (e.g., electrons) such as through ECD, EID, or EIEIO. The kinetic energy of the charged species is such that the fragments may be detected and produce spectra that allow for the determination of isomeric species in the sample and the location of double bonds of sample molecules. The fragments may include radical fragments and non-radical fragments. The apparatus may also include an oxygen gas source configured to react with the radical fragments to produce oxygen-radical fragments. Spectra resulting from analysis of the fragments may allow for the determination of the oxygen-radical fragments resulting from the dissociation of the sample molecules. |
