Mass spectrometer and method of analyzing isomers |
| abstract |
The invention intends to determine a presence ratio between mixed compounds which are difficult to separate from each other by a separation unit and cannot be discriminated by MS. In a mass spectrometer with an MS n analysis function for ionizing a sample eluted from a separation unit for separating the sample into individual components, fragmenting an ion of a desired mass number, and performing a mass analysis of fragment ions, the mass spectrometer includes a database storing correlation information between an isomer presence ratio and a particular ion intensity ratio in a mass spectrum per isomer. An isomer ratio can be clarified even for a mixed sample of isomers, such as enantiomers, which are difficult to separate from each other by the separation unit and cannot be discriminated by MS. |
